Initialising of CommonsHttpSolrServer in Spring framwork

[Ranjeet]

Hi,

I am using Solr 1.3 and Solrj as a Java Client. I am Integarating Solrj in 
Spring framwork, I am facing a problem, Spring framework is not inializing 
CommonsHttpSolrServer class, how can  I define this class to get the instance 
of SolrServer to invoke furthur method on this. 

Thanks & Regards,

Hi Ranjeet,
try this in your Spring config:



  http://solr_url:8080/

  

  

  





and inject it to you service like this:



  

  



and you have to have a setter in SomeService for the prop. server
(solrServer), off course.

Hope this helps,

[Lukáš Vlček]

Hi,

Either I didn't get the BCc email or it ended in trash folder (gmail spam
filter?) without me noticing it.
If there is a still room for new log design for Solr and the community is
open for it then I can try to come up with some proposal. Doing logo for
Mahout was really interesting experience.

Just let me know what is the status.

Lukas

[Fuad Efendi]

Use constructor and pass URL parameter. Nothing SPRING related... 

Create a Spring bean with attributes 'MySolr', 'MySolrUrl', and 'init'
method... 'init' will create instance of CommonsHttpSolrServer. Configure
Spring...

dismax and standard query types

[Jae Joo]

If there any way to mix dismax and standard query type?

Here is the example..

(wendys columbus) AND state:Georgia

wendys columbus --> qt=dismax

Thanks,

Jae Joo

One option is to use "wendys columbus" as the q parameter, and  
state:Georgia as a fq (filter query) parameter.

Re: dismax and standard query types

[Smiley, David W. (DSMILEY)]

I have done so with some hacking but Solr doesn't support this natively.  If
you did a mailing list search, you may of turned up this:

http://www.nabble.com/Standard-vs.-DisMaxQueryHandler-td6421205.html#a169458

I'm presently trying to get permission from my employer to release my
modifications to Solr.

Looks to me like you have a conflict with the version of HttpClient in

diversity in results

[Jason Rennie]

Is there any option in solr to encourage diversity in the results?  Our solr
index has millions of products, many of which are quite similar to each
other.  Even something simple like max 50% text overlap in successive
results would be valuable.  Does something like this exist in solr or are
there any plans to add it?

Thanks,

Jason

Sum of one field

[Leonardo Dias]

Everyone exhibits "your search for x has returned y results" on the top 
of the results page, but we need something else, which would be 
something like "your search for x returned y results in z records", 
being z the numdocs of the SOLR response and y a SUM(quantity) of all 
returned records.


In SQL you can do something like:

SELECT count(1), sum(quantity) FROM table

But with SOLR we don't know how can we do the same without having to 
return all the XML result for the field "quantity" and then sum it to 
show the total. Any hints on how to do it in a better way?




cheers,

Leonardo

Re: Sum of one field

[Otis Gospodnetic]

Leonardo,
You'd have to read that "quantity" fields for all matching documents one way or 
the other.
One way is by getting all results and pulling that field out, so you can get 
the sum..
Another way is to hack the SolrIndexSearcher and get this value in one of the 
HitCollector collect method calls.
Another possibility, if your index is fairly static, might be to read it all 
documents' (not just matches') quantity field and store that in a 
docID->quantity map structure that lets you look up quantity for any docID you 
want.


There may be other/better ways of doing this, but this is what comes to (my) 
mind first.

not out of the box, but I would use the mlt handler on the first

Re: diversity in results

[Jason Rennie]

Does the MLT handler simply select a few high tfidf terms from the doc and
use them as a query?  Sounds like a useful tool.  Do you know anything about
relevant performance issues?  I noticed that the Solr MoreLikeThis wiki page
recommends turning on TermVectors for corresponding fields.  Can lucene not
easily return term counts for a document with the standard indexing b/c it's
term-based (i.e. "inverted").  Does TermVectors=true cause solr/lucene to
store an additional doc-based index?

Thanks,

Jason

Re: diversity in results

[Otis Gospodnetic]

Hi Jason,


Yes, TV will store additional data in the index.  Using fields with TV=true 
will simply get to the seminal terms more easily.  Yes, in the end the terms 
are used to perform a normal query and get the most similar docs.  This is 
based on my use of MLT a whiiile back, but I don't think things changed 
that much in the last few years.

Correct.


Does TermVectors=true cause solr/lucene to
store an additional doc-based index?


Yes, that is correct

if 'y" doesn't have to be extremely precise, you could query say, 50 records,
get the y out of this and extrapolate. You may end up with 'your search for x
returned aproximately y results in z records'. You could keep that information
(the approximate value of y)  in some cached object outside of SOLR and reuse
it for popular searches.

I say 50 records, but maybe you can get a good approximation with 10 only.

+1 

If we are going to change what we have, i'd love to see some more options , or
better quality - no offence meant , but those "logos" aren't really a huge
improvement or departure from the current one. 

I think whatever we change to we'll be wanting to use it for a long time.

solr 1.3 ??

[Vicky_Dev]

Hi

Any ideas on when 1.3 might be released? 

In solr 1.3, there are really good features like--DataImportHandler which I
want to use in my project. Trunk folder is changing regularly. 

Can we get solr 1.3 release as soon as possible? Otherwise some interim
release (1.2.x) containing DataImportHandler will also a good option. 

Any Thoughts?

have you tried one of the nightly builds? I've been following it every so
often...sometimes there is a problem, but hardly ever... you can find a build
you are comfortable with, and it'll be far closer to the actual 1.3 when
released than 1.2 .
