Re: Documentation?
I read a bit "Lucene in action" with a lot of nice example and was very optimistic to use solr, but i was really disappointed when I was looking for documentation for solr - even the javadoc is very poor, no explanation of the framework, about why there are so many different classes with similar names, everything is just confusing! I think, if somebody would have invested 1% of the time creating solr in his documentation, solr could be very easely used by everyone. I am not an expert in search engine, and i also don't think that the framework of solr is so complicated, but without documentation I just feel lost. What i really want to do is a kind of "custom sorting" very similar to that "DistanceComparator" example from "Lucene in Action", but there is really no examples out there how to do that... I admit, my own code most of time is not looking much better, but for such a big project i really expected much more documentation and comments for the api.

Re: Custom Sorting
I have the same problem, also need to plugin my "customComparator", but as
there is no explanation of the framework, how a RequestHandler is working,
what comes in, what comes out ... just impossible!
Can someone explain where i have to add which code, to just have the same

Re: Documentation?
Markus, as we are all volunteers here, nobody is paid to write code and documentation. Everybody scratches their own itch. Complaining won't do a lot of good here. Most of Solr is not meant to be consumed as an API and therefore there is a general lack of javadocs. Solr is generally used through configuration and consumed over HTTP so you will find a lot of documentation on each of the supported features. There is a lot of documentation on the wiki at http://wiki.apache.org/solr . However the use-case you have is quite rare and therefore not very well documented. However, you will find that people are helpful if you are willing to give them a chance. Starting a conversation in this tone will be a disadvantage.

I do not know much about this but I can see that the org.apache.solr.handler.component.QueryElevationComponent inside Solr uses a custom sort to push documents at the top of the results.

Re: Custom Sorting
Markus,
A couple of code pointers for you:
* QueryComponent - this is where results are generated, it uses a
SortSpec from the QParser.
* QParser#getSort - creating a custom QParser you'll be able to
wire in your own custom sort
You can write your own QParserPlugin and QParser, and configure it
into solrconfig.xml and should be good to go. Subclassing existing
classes, this should only be a handful of lines of code to do.

Flipping data dirs for an (/multiple) SolrCore without affecting search / IndexReaders
We have an architecture where we want to flip the solr data.dir (massive
dataset) while running and serving search requests with minimal downtime.
Some additional requirements.
* While ideally - we want the Solr Search clients to continue to serve
from the indices as soon as possible -the overriding requirement is that
the downtime for the Search Solr instances should be as less as
possible.So when a new set of (Lucene) indices come in - the
algorithm we are experimenting with:
- create a new solrcore instance with the revised data directory.
- warm up the solrcore instance with some test queries.
- register the new solrcore instance with the same name as the old one,
so that all new queries from the clients are to the new SolrCore instance.
- As part of register (String, SolrCore, boolean ) - the III parameter
when set to false , closes the core connection.
I am trying to understand more about the first and the fourth ( last)
steps.
1) What is the fastest / best possible way to get step 1 done ,through a
pluggable architecture.
Currently - I have written a request handler as follows, that takes care
of creating the core. What is the best way to change dataDir (got as
input from SolrQueryRequest) before creating SolrCore-s.
public class CustomRequestHandler extends RequestHandlerBase implements
SolrCoreAware
{
private CoreDescriptor coreDescriptor;
private String coreName;
@Override
public void handleRequestBody(SolrQueryRequest req,
SolrQueryResponse rsp) throws Exception
{
CoreContainer container = this.coreDescriptor.getCoreContainer();
// TODO: Parse XML to extract data
// container.reload(this.coreName);
// or
// 2.
// TODO: Set the new configuration for the data directory / before
creating the new core.
SolrCore newCore = container.create(this.coreDescriptor);
container.register(this.coreName, newCore, false);
}
@Override
public void inform(SolrCore core)
{
coreDescriptor = core.getCoreDescriptor();
coreName = core.getName();
}
}
2) When a close() happens on an existing SolrCore - what happens when
there is a long running IndexReader query on that SolrCore . Is that
terminated abruptly / would the close wait until the IndexReaders
completes the Query.
* The same process is repeated potentially for multiple SolrCores as
well, with additional closeHooks that might do some heavy i/o tasks -
talking over the network etc.
Right now - these long running processes are done in an independent
thread so that they do not block SolrCore.close() with the currently
nightly builds.

Solrj client - CommonsHttpSolrServer - getting solr.solr.home
I am reading the wiki here at - http://wiki.apache.org/solr/Solrj . Is there a requestHandler ( may be - some admin handler ) already present that can retrieve the solr.solr.home for a given CommonsHttpSolrServer instance ( for a given solr endpoint), through an api.
Re: Some solrconfig.xml attributes being ignored
Mark,
Looked at the code to discern this...
A fragmenter isn't responsible for the number of snippets - the higher
level SolrHighlighter is the component that uses that parameter. So
yes, it must be specified at the request handler level, not the
fragmenter configuration.

Accessing multiple core via cross context queries.
Hi All,
I'm developping a webapp that needs access to the solr webapp.
I can get my solr context like that:
ServletContext solrContext = getServletContext().getContext("/solr");
but when I do
solrContext.getRequestDispatcher("/core0/select/").dispatch(request,response)
;
I get a 404 error:
HTTP Status 404 - /solr/core0/select/

Beside that, if access /solr/core0/select/ directly then everything is fine.
>From what I saw in the sources , solr relies on a Filter notion to
deal with queries involving multicore, but I cannot see why this could
have an influence on what resources is available from the eyes of who.
Can't a webapp see the same things as the web users does ? j2ee gurus help !
Is there something I'm missing here ? (both webapps are with crossContext=true )
Cheers!

Re: Unwanted clustering of search results after sorting by score
: Max - field collapsing may be your friend - https://issues.apache.org/jira/browse/SOLR-236 that doesn't really seem related ... i don't believe Max wants to see all results from a store "collapsed" into on result, i think he wants to see results from differnet stores treated "more fairly" and to eliminate the clustering effect he's seeing where differnet products from the same store tend to have similar scores because of the way the store provides the data (and not because of any inherent relevancy of hte proudcts) Max: to really diagnose something like this, you have to consider all the details about what exactly your queries look like and spend a lot of time looking at score explanations to really get a sense for the "trend" of why certain stores score higher then others. off the cuff, the only thing i can comment on is this specific example you made... : > Shop 'foo' describes its products with 250 words and uses the searched : > word once. Shop 'bar' describes its products with only 25 words and also : > uses the searched word once. The score for shop 'foo' will be much worst : > than for shop 'bar'. In a search in which are many products of shop : > 'foo' and 'bar' the products of shop 'bar' are shown before the products : > of shop 'foo'. depending on how you look at it, 'foo' is spamming you with excess keywords and bar deserves to get higher scores. eliminating "tf" probably isn't wise, but you might want to consider omiting norms, so the length of hte field doesn't factor in ... or you might want to try customizing your lengthNorm function (requires writing a SImilarity class) to make it flatter for 25-250 terms, but have a sharp spike if they go above 250 (if you consider 250 the threshold for a product description before you decide it's "spam"). You could also consider adding a numeric "shop_fudge_factor" field that you populate with a number indicating the average number of terms in product descriptions from that shop (you'd have to compute this yourself and add it to every document) and then use that as part of a FunctionQuery to fudge the scores for stores that are long winded a little higher. I would never do that personally though (it encourages keyword spamming in product descriptions) but it's something you can try. A suggestion of *least* resort: if you customize your Similarity class such that all the methods round the score components to very course granularity (ie: 1.2 instead of 1.234567) you should wind up with more tight groupings of products with the *exact* same score ... you could then do a secondary sort on something else (random perhaps?) to try and make the ordering more fair. (i really have no idea how well that might work) -Hoss
php client. json communication
Hi, I am about to integrate solr for index/search of my documents/data. It's php application but I see it should be no problem as solr works with xml by default. Is there any read php lib that will ease/help whole communication with solr and if possible to send/receive json data. I looked up archive list and seems not many discussions in php. Also from manual it seems that it can only get json response but request should always be xml. Cheers,

Re: Boosting by date when only some records have one

That covers the possiblility that hasDateField is not set for some docs.
The query get's simpler if you can concretely know that hasDateField will
always have a value of true or false...

RequestHandler lifecycle in a Multiple SolrCore context
If I have a CustomRequestHandler that inherits from RequestHandlerBase implementing SolrCoreAware interface - what is the lifecycle of the invocation of method - inform(SolrCore) in a multiple SolrCore context . Would it be that we have separate instances of RequestHandlers created for each SolrCore. Can somebody add more information about the same.

umlaut index ö == o == oe Possible?
Hi, I am just going through http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters and maillist archive but somehow can't find the solution. Is it possible that I treat 'möchten' , 'mochten' and 'moechten' the same way. Of course not hardcoding this but rather work for any umlaut. Cheers
Re: umlaut index ö == o == oe Poss ible?
I believe the german porter stemmer should handle this. I haven't used it with SOLR but I've used it with other projects, and basically, when the word is parsed, the umlauts and also accented vowels are converted to plain vowels. I guess with SOLR you use solr.SnowballPorterFilterFactory: http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#head-b80fb581f4e078142c694014f1a8f60c0935e080 with the German option (like in their example). You probably want to apply this both at index and query time. -- Steve On Dec 16, 2008, at 6:02 PM, Julian Davchev wrote: Hi, I am just going through http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters and maillist archive but somehow can't find the solution.

Hmm ... i thought this was an offshoot question ... the main point of this
thread seems to have already been solved by the new
ext.literal.${fieldname}=${fieldvalue} param support Grant just added
to ExtractingRequestHandler right?
what am i missunderstanding about the usecase that isn't solved by that?
the "tika doc" from the ContentStream is the primary "guts" of the doc,
with additional literal "metadata" fields being added, correct?
(I can imagine a more complicated usecase where someone might want a
single document built from multiple ContentStreams parsed by Tika, with
differnet pieces of each TikaDoc contributing in differnet ways ... ie: my
name is Hoss, my address is X, my phone number is Y, this
first ContentStream should be indexed as my bio field (doesn't matter if
it's PDF, HTML, MS-Word, etc.), index and store the ID3 Title & length
from any MP3 ContentStreams in the multivalued "lecture_title" and
"lecture_length" fields, and any ContentStreams left over should be
indexed in the misc "other_text" field. but that's not what we're
talking about here, correct?)

Re: Boosting by date when only some records have one
Hi,
thanks a lot! Looks like what I need except that I cannot use dismax
because I need to be able to do prefix queries. I'm new to Solr, so I
don't know if there's a way to formulate this in a standard query. If
not, I could extend DismaxRequestHandler so it doesn't escape the "*"s,
right?

Is making removal of wildcards configurable planned for DisMaxRequestHandler
Hi, I'm rather new to Solr and for my current projects came to the conclusion that DisMaxRequestHandler is exactly the tool I need, except that it doesn't allow prefix queries. I found a thread in the archive were someone mentioned the idea of making this behaviour configurable (which characters to strip from the query parameter). Is someone working on this or is my best option currently to implement this behaviour by copying code from DisMaxRequestHandler and modify the code that strips illegal operators?
