Re: FunctionQuery score=0
After playing some more with this I managed to get what I want, almost.
My query now looks like:
q={!frange l=0 incl=false}query({!type=edismax qf="abstract^0.02 title^0.08
categorysearch^0.05" boost='eqsim(alltokens,"xyz")' v='+tokens5:"xyz" '})
With the above query, I am getting only the results that I want, the ones
whose score after my FucntionQuery are above 0, but the problem now is that
the final score for all results is changed to 1, which affects the sorting.
How can I keep the original score that is calculated by the edismax query?
Cheers,
John

You have of course started with the basics like making sure that the index is less than available RAM on your server? (Or index-size per shard is less than available RAM on the server if you are running a multi server cluster) As long as your index is bigger than what can be placed in cache you will have a hard time keeping your queries fast no matter what, unless the search queries are few enough that they are always within Solr`s own query cache. -- Regards Tor Henning Ueland
how to transform a URL (newbie question)
I am a beginner to solr and need to ask the following: Using the apache-solr example, how can I display an url in the xml document as an active link/url in http? Do i need to add some special transform in the example.xslt file? thanks Ben - No virus found in this message.

Re: how to transform a URL (newbie question)
Ben, Not quite sure how to interpret what you're asking here. Are you speaking of the /browse view? If so, you can tweak the templates under conf/velocity to make links out of things. But generally, it's the end application that would take the results from Solr and render links as appropriate.

RE: how to transform a URL (newbie question)
Erik, OK, I will look at that. Basically, what I amtrying to do is to index a document with lots of URLs. I also index the url and give it a field type. Don't know much about solr yet, but though maybe I can transform the url to an active link, i.e. ''. I tried putting the href into the xml document, but it just prints out as text in html. I also could not find any xslt transform or schema. thanks Ben -Original Message- From: Erik Hatcher [mailto:erik.hatc...@gmail.com] Sent: Sunday, November 20, 2011 9:05 AM To: solr-user@lucene.apache.org Subject: Re: how to transform a URL (newbie question) Ben, Not quite sure how to interpret what you're asking here.

Re: wild card search and lower-casing
As it happens I'm working on SOLR-2438 which should address this. This patch
will provide two things:
The ability to define a new analysis chain in your schema.xml, currently called
"multiterm" that will be applied to queries of various sorts,
including wildcard,
prefix, range. This will be somewhat of an "expert" thing to make yourself...
In the absence of an explicit definition it'll synthesize a multiterm analyzer
out of the query analyzer, taking any char fitlers, and
lowercaseFilter (if present),
and ASCIIFoldingfilter (if present) and putting them in the multiterm
analyzer along
with a (hardcoded) WhitespaceTokenizer.
As of 3.6 and 4.0, this will be the default behavior, although you can
explicitly
define a field type parameter to specify the current behavior.
The reason it is on 3.6 is that I want it to bake for a while before
getting into the
wild, so I have no intention of trying to get it into the 3.5 release.
The patch is up for review now, I'd like another set of eyeballs or
two on it before
committing.
The patch that's up there now is against trunk but I hope to have a 3x
patch that
I'll apply to the 3x code line after 3.5 RC1 is cut.

Re: Solr filterCache size settings...
Each fq will create a bitmap that is bounded by (maxdocs / 8) bytes. You can think of the entries in the fiterCache as a map where the key is the filter query you specify and the value is the aforementioned bitmap. The number of entries specified in the config file is the number of entries in that map. So the cache can take up roughly (assuming the size if 512) 512 * maxDocs / 8 bytes.

Re: Can files be faceted based on their size ?
Well, I wouldn't store it as a string in the first place. Otherwise, you're right, you have to store it as an entity that compares lexicographically, usually by left-padding with zeroes. But don't do that if at all possible, it's much more expensive than storing ints or longs, so can you re-index these as one of the Trie* types?

Re: how to transform a URL (newbie question)
I think you're confusing Solr with a web app Solr itself has nothing to do whatsoever with presenting things to the user. It just returns, as you have seen, XML (or JSON or ) formatted replies. It's up to the application layer to do something intelligent with those. That said, the /browse request handler that ships with the example code uses something called the VelocityResponseWriter to render pages, where the VeolcityResponseWriter interacts with the templates Erik Hatcher mentioned to show you pages. So think of all the Velocity stuff as your app engine for demo purposes. Erik is directing you at that code if you want to hack the Solr example to display stuff. Hope that helps Erick (not Hatcher ) On Sun, Nov 20, 2011 at 2:15 PM, Bent Jensen wrote: > Erik, > OK, I will look at that.

Pagination problem with group.limit=2
Hi, As per our business logic we have to show two products per company in our results. Second product should also be displayed as a normal search result, instead of "more..." (or "+", "expand") kind of nested results. *Short description*: With *group.limit=2 *option I am not able to find the exact number of results (not groups) that will be returned in the output on increasing start/rows parameters. Is there any solution? *Detailed description*: We are using solr 3.4 with following group options group=true group.field=company group.limit=2 group.format=simple group.ngroups=true I have following company wise count in index against search criteria company1 = 1 products company2 = 2 products company3 = 3 products company4 = 4 products Now I get a result with following figures matches:10 ngroups:4 doclist.numFound:10 But actual results returned are different (7 results). At max there can be 4x2 (= 8 ngroups x limit) products in the result but company1 returns just 1 results. Others return 2 results each. Now My question is how can I find this actual number so that I can display correct page numbers? I searched for it but there were very few threads regarding the exact issue and those too were old. Any help or pointer is appreciated. -- Regards, Samar

Do you think the patch you are working on will be applicable as well to 3.4?

Solr Performance/Architecture
Number of rows in SQL Table (Indexed till now using Solr): 1 million Total Size of Data in the table: 4GB Total Index Size: 3.5 GB Total Number of Rows that I have to index: 20 Million (approximately 100 GB Data) and growing What is the best practices with respect to distributing the index? What I mean to say here is when should I distribute and what is the magic number that I can have for index size per instance? For 1 million itself Solr instance running on a VM is taking roughly 2.5 hrs to index for me. So for 20 million roughly it would take 60 -70 hrs. That would be too much. What would be the best distributed architecture for my case? It will be great if people may share their best practices and experience.
