Re: Huge load and long response times during search
Hi, Otis Gospodnetic pisze: Tom, It looks like the machine might simply be running too many things. > If the load is around 1 when Solr is not running, and this is a dual-core server, it shows its already relatively busy (cca 50% idle). The server is running the Postgresql and Apache/PHP as well, but without solr the server condition is more than good (load usually less than 1, sometimes , even dring rush hours we observed 1m load avg 0,68). It is double dual core so load 1 means 25% am I right (4 cores)? Your caches are not small, so I am guessing you either have to have a relatively big heap, or your heap is not large enough and it's the GC that's causing high CPU load. The java starts with Xmx3584m. Should that be fine for such cache settings? By the way I'm wondering if we need such caches. I did check query frequency for last 10 days (~7 unique users) and most frequent phrase appears ~150 times, and only 11 queries exists more than 100 times. I did not count if user used the same query but goes to next page. Is this worthy to keep quite big cache in this cas? If you are seeing Solr causing lots of IO, that's a sign the box doesn't have enough memory for all those servers running comfortably on it. We do have some free memory to use. Server has 8G RAM and mostly uses up to 6G, I haven't seen the swap used yet. I would try to give more RAM for java and use smaller cache to see if it would work. Tom
Re: Index time boosts, payloads, and long query strings
Thanks Erick! After reading your answer, and re-reading the Solr wiki, I realized my folly. I used to think that index-time boosts when applied on a per-field basis are equivalent to query time boosts to that field. To ensure that my new understanding is correct , I'll state it in my words. Index time boosts will determine boost for a *document* if it is counted as a hit. Query time boosts give you control on boosting the occurrence of a query in a specific field.

Yeah, like I said, I was mistaken about setting field boost in schema.xml - doesn't mean it's a bad idea though.

Re: Huge load and long response times during search
Tom, AFAIK Lucene performance is very much dependent on file system cache size, in case of large index. So if you see lots of IO, this probably means that your system doesn't have enough memory to hold large file system cache, suitable for your index size. In this case you don't need to give more memory to java processes, but instead you need to free as much memory as you can for the OS.

Boost document base on field length

Override the default Similarity (see the end of the schema.xml file) with your own Similarity implementation and then in that class override the lengthNorm() method.

If the query is unrestricted by other clauses or by filters, yes it will

Which part? The hsin() part calculates the distance between the point 0.57,
-1.3 and the values in the fields lat_rad, lon_rad and is using 3963.205 as the
radius of the sphere (which is the approx. radius of the Earth in miles). The
frange stuff then filters such that it only accepts docs that have a value for
hsin between 0 and 400.

The query function just allows you to use any other query type inside a function query. So you could add or multiply the scores of two dismax queries together, or whatever. As far as practical usecases... I've used it for selectively boosting one query based on the results of another query. I'm sure others will find other uses for it. -Yonik http://www.lucidimagination.com

Re: error with multicore CREATE action
Are there any use cases for CREATE where the instance directory
*doesn't* yet exist? I ask because I've noticed that Solr will create
an instance directory for me sometimes with the CREATE command. In
particular, if I run something like
http://solrhost/solr/admin/cores?action=CREATE&name=newcore&instanceDir=d:\dir_that_does_not_exist\&config=C:\dir_that_does_exist\solrconfig.xml&schema=C:\dir_that_does_exist\schema.xml
then Solr will create
d:\dir_that_does_not_exist
and
d:\dir_that_does_not_exist\data
for me (but not d:\dir_that_does_not_exist\conf).
Maybe this has to do with some particularly in my solrconfig.xml?
(There I've commented out the dataDir element because I prefer the
default behavior to what you get with "${solr.data.dir:./solr/data}".)

Re: Fwd: solr index-time boost... help required please
: Now I am trying *index-time *boosting to improve response time. So i created : an algorithm where I do the following:- : 1. sort the records i get from database on approval_dt asc and increase the : boost value of the element for approval_dt by 0.1 as i encounter : higer approval_dt records. If there is no approval_dt for a record, not : boost value for it. I made omitnorms=false in schema.xml for approval_dt : field. Now when I apply the same query nothing special happens ie I dont : even see the latest dates first. index time boosting of a field just affects tehfieldNorms for the specific field you apply the boost too -- if you don't search on that field (with a score based query type), the boost doesn't affect things. so if you applied an index time boost to some field named "approval_dt" then that boost isn't going to matter unless you query against the approval_dt field -- but if you use something like a range query, the boost still won't matter because range queries don't affect the score. more then likely what you want to do is use a *document* boost instead of a field boost .. that way the boost factor gets applied to any field you have that includes the norms, so no matter what field you query on the boost will get applied. : 2. If we boost a doc or field in the xml should we again use the bf : parameter with a function to put the boost into effect while querying when : trying index-time boost also? index time boosts and query boosts are completley orthoginal, you can use both together, but they don't require (or know) about eachother at all : 3. Also can you frame a query for me to see the latest approval_dt coming : first using the index-time boost approach. not with the setup you've described ... date based queries really won't ever look at the norms for the data field (unlessy ou did a term query for a very specified date value) : 4. Does bf function play any role in solrconfig.xml when we plan to use : index-time boost. My understanding is bf is used only for query-time boost. you are correct. : 5. Is it necessary to use bq in case of index time boost. same answer as #2. -Hoss

I then issued a curl command to rebuild the spellcheck index (I also did a full-import & reload of the main index, to be safe.) When this error occured, our solrconfig.xml had spellcheck.build set to true. This was a configuration eror on our part. I was wondering if the spellcheck index being re-built for each query could have caused the above exception to occur. Kind clarify.

help with dataimport delta query
Hi, I have solr all working nicely, except im trying to get deltas to
work on my data import handler
Here is a simplification of my data import config, I have a table
called "Book" which has categories, im doing subquries for the
category info and calling a javascript helper. This all works
perfectly for the regular query.
I added these lines for the delta stuff:
deltaImportQuery="SELECT f.id,f.title
FROM Book f
f.id='${dataimporter.delta.job_jobs_id}'"
deltaQuery="SELECT id FROM `Book` WHERE fm.inMyList=1 AND
lastModifiedDate > '${dataimporter.last_index_time}'" >
basically im trying to rows that lastModifiedDate is newer than the
last index (or deltaindex).
I run:
http://localhost:8983/solr/dataimport?command=delta-import
And it says in logs:

But the browser says no documents added/modified (even though one

Is there a way to turn debugging so I can see the queries the DIH is

Any other ideas of what I could be doing wrong?

Complex multi-value boosting
Guys -- What schema will you use for 500K docs with a variety of 0-30 different category ids, each carrying its own weight and completely overriding the default scoring? For example, these documents: A: 1:0.21, 2:0.41, 3:0.15 ... B: 1:0.18, 2:0.65 4:0.98 ... C: 6:0.75 ... D: 2:0.14 ... When searching "1" I'd like document A to appear first (has 0.21) and when searching "1 || 2" i'd like document B to appear first (has an aggregate score of 0.83 vs. 0.62). Currently I run this with full-text after artificially repeating the number of each category's weight (i.e. "1" would appear 21 times on a text field) - is there a better way? Best, -- Michael
RE: Multi word synonym problem
: The response is not searching for Michael Jackson. Instead it is : searching for (text:Micheal and text: Jackson).To monitor the parsed : query, i turned on debugQuery, but in the present case, the parsed query : string was searching Micheal and Jackson separately. using index time synonyms isn't ggoing to have any effect on how your query is parsed. the Lucene/Solr query parsers uses whitespace as "markup" and will still analyze each of the "words" in your input seperately and build up a boolean query containing each of your words individually (the only way to change that is to use quotes to force "phrase query" behavior where everything in quotes is analyzed as one chunk, or pick a different queyr parse like the "field" parser) ...but none of that changes the point of *why* you can/should use index time synonyms for situations like this. the point of doing that is that at index time the alternate versions of the multi-word sequences can all be expanded and all varients are put in the index ... so it doesn't matter if you use a phrase query, or term queries, all of the synonyms are in the index document. -Hoss

H, One of us massivly missunderstood the original question - and i'm

i don't think he wants results where the user field plus the num field are
in the range of 5-10 ... i think he wants the list of user Ids (which are
numbers in his examples, but could just as easily be strings) where the
sum of the "num" fields in all documents that have the same value in the
"user" field are the same.
I can't think of any easy way to do that ... it isn't the kind of thing an
Inverted Index is particuaraly good at. but maybe there's soemthing in
the Field Collapsing patch (searching the archives/wiki will bring up
pointers) that can filter on stats like this?

ExternalRequestHandler and ContentStreamUpdateRequest usage
Following code is from my test case where it tries to index a file (of type
.txt)
ContentStreamUpdateRequest up = new
ContentStreamUpdateRequest("/update/extract");
up.addFile(fileToIndex);
up.setParam("literal.key", "8978"); //key is the uniqueId
up.setParam("ext.literal.docName", "doc123.txt");
up.setAction(AbstractUpdateRequest.ACTION.COMMIT, true, true);
server.request(up);
test case doesn't give me any error and "I think" its indexing the file? but
when I search for a text (which was part of the .txt file) search doesn't
return me anything.
Following is the config from solrconfig.xml where I have mapped content to
"description" field(default search field) in the schema.
description

Clearly it seems I am missing something. Any idea?

Re: Embedded solr with third party libraries
To deploy the Lucid KStem stemmer, copy these two files: lucid-kstem.jar lucid-solr-kstem.jar to the lib/ directory in your running solr instance. In the declaration for a text field, you would change this line: to this: (Remember that you have to make this change in both the query and analysis sections of the fieldType specification.) Now, to verify the change, restart solr and go to the analysis.jsp test page: http://localhost:8983/solr/admin/analysis.jsp Let's say you changed the 'text' type and left 'textTight' using PorterStemmer. Change the Field name/type drop-down to 'type' and type 'text' in the top box. Now type 'changing' in the "Field Value" box and click 'Analyze'. The bottom of the page will now show that 'changeing' was stemmed to 'change'. If you change the field type from 'text' to 'textTight' and try again, 'changing' will be stemmed to 'chang' by the original PorterStemmer.

What do your logs show? Else, what does Luke show or doing a *:* query
(assuming this is the only file you added)?
Also, I don't think you need ext.literal anymore, just literal.

After fiddling with the position incremements stuff I upped the query
slop to 2 which seems to now provide better results but I'm worried
about that effecting relevancy elsewhere (which I presume is the reason
why it's not the default value).
If that's the case - is it worth writing something for my app so that if
it detects a phrase query with lots of stop words it ups the phrase
slop?
Either way it seems to be working now - thanks for all the help,

Re: ExternalRequestHandler and ContentStreamUpdateRequest usage
FYI: weirdly its returning me following when I run
rsp.getResults().get(0).getFieldValue("description")
[702, text/plain, doc123.txt, ]
so it seems like its storing
up.setParam("ext.literal.docName", "doc123.txt"); into description versus
file content in "description" attribute.
Any idea?

Re: help with dataimport delta query
got to love it when yahoo thinks your own mail is spam, anyone have
any ideas how to get logging to work with 1.4.
I went to the admin panel and set all logging to finest.
In my jetty std out I see no SQL for any of the dataimport handler
run. I see
Nov 23, 2009 9:26:27 PM
org.apache.solr.handler.dataimport.JdbcDataSource$1 call
INFO: Time taken for getConnection(): 6
Nov 23, 2009 9:26:32 PM
org.apache.solr.handler.dataimport.JdbcDataSource$1 call

localhost/feeddb
Nov 23, 2009 9:26:32 PM
org.apache.solr.handler.dataimport.JdbcDataSource$1 call
INFO: Time taken for getConnection(): 5
But no sql, from looking at the source, it looks like it should be
logging the sql if Im in debug mode.
any ideas, I think I am losing my mind.
my full import works, but the delta does nothing
thanks

Implementing phrase autopop up
hello all Let me first explain the task i am trying to do. i have article with title for example >Car Insurance for Teenage Drivers − A Total Loss? If a user begins to type car insu i want the autopop to show up with the entire phrase. There are two ways to implement this. First is to use the termcomponent and the other is to use a field with field type which uses solr.EdgeNGramFilterFactor filter. I started with using with Term component and i declared a term request handler and gave the following query http://localhost:8080/solr/terms?terms.fl=title&terms.prefix=car The issue is that its not giving the entire pharse, it gives me back results like car, caravan, carbon. Now i know using terms.prefix will only give me results where the sentence start with car. On top of this i also want if there is word like car somewhere in between the title that should also show up in autopop very much similar like google where a word is not necessarily start at the beginning but it could be present anywhere in the middle of the title. The question is does TermComponent is a good candidate or using a custom field lets the name is autoPopupText with field type configured with all filter and EdgeNGramFilterFactor defined and copying the title to the autoPopupText field and using it to power autopopup. The other thing is that using EdgeNGramFilterFactor is more from index point of view when you index document you need to know which fields you want to copy to autoPopupText field where as using Term component is more like you can define at query time what fields you want to use to fetch autocomplete from. Any idea whats the best and why the Term component is not giving me an entire phrase which i mentioned earlier. FYI my title field is of type text.

Hello Solr users, is there a live demo of the auto-completion feature somewhere? thanks in advance paul
Re: help with dataimport delta query
I guess the field names do not match
in the deltaQuery you are selecting the field id
and in the deltaImportQuery you us the field as
${dataimporter.delta.job_jobs_id}
I guess it should be ${dataimporter.delta.id}

You should use a non-tokenized type (such as a string type) with TermsComponent. However, this will only let you search by prefix and not by words in between the phrase. Your best bet here would be to use EdgeNGramFilterFactory. If your index is very large, you can consider doing a prefix search on shingles too. -- Regards, Shalin Shekhar Mangar.

Think of something like title:searchstring^10 OR catch_all:searchstring Of course I can always add the boosting at query time but it would make life easier if I could define a default boost in the schema so that my query could just be title:searchstring OR catch_all:searchstring but still get the boost for the title field. Thinking this further it would be even better if it was possible to define one (or more) fallback field(s) with associated boost factor in the schema. Then it would be enough to query for title:searchstring and it would be automatically expanded to e.g. title:searchstring^10 OR title_other_language:searchstring^5 OR catchall:searchstring or whatever you define in the schema. -Michael

Rebuilding the index for each query is not a good idea anyways. -- Regards, Shalin Shekhar Mangar.
