query parser attaches "text:" prefix to query

[Matthias Müller]

Hi,

when I request a query to solr with
/solr/select?q=query&debugQuery=true&qf=title
I get no result.

The debug information tells me this.

query
text:query

When I request a query to solr with /solr/select?q=title:query&debugQuery=true
I get the desired result.

title:query
title:query

The debug information tells me this.

Why does the quey parser attach text: to the user query so that the qf
parameter is ignored?

Solr Specification Version: 3.4.0.2011.09.09.09.06.17

QueryHandler:
org.apache.solr.handler.component.SearchHandler
version: $Revision: 1052938 $

QueryHandler Config:
  
 
   title
 
  

Kind Regards

Matthias

Wildcard query with uppercase characters gets no result in edismax handler

[Matthias Müller]

Hi,

I'm using an edismax handler
All fields and queries are lower case (LowerCaseFilterFactory in schema.xml)

Queries for television, Television and televisio* lead to results.
But Televisio* has no result.

Is this a bug, a feature or a misconfiguration?

Kind Regards

Stop Words in SpellCheckComponent

[Matthias Müller]

Hi,

is it possible to configure a stopword list to the SpellCheckComponent?

For example:
When searching for "the indexs" "the" is filtered, because it is a stopword.
The SpellCheckComponent gives me a false suggestion for "the".
But the SpellCheckComponent should only give a suggestion for "index"
because "the" is a stopword.

Kind Regards

Matthias

Hmm, I did. Could it be another mistake?

This is the schema definition:


  





  


This is the solrconfig:

  
 
   edismax
   10
   text_de title_de^5
   text_de title_de^5

   true
   0
 

 
   spellcheck_de
 
  


  
textSpell

  default
  spellcheck_de
  spellchecker_de
  true
  true

Thanks for your help. But I did that, too.

Here I'll show that even the solr example webapp makes suggestions for
stopwords: I've ...

1. added "the" to the stopwords.txt
2. added "thex" to an example document (field name)
3. startet solr
4. indexed the example files (sh post.sh *.xml)
5. searched for "the solr"
http://myhost:8983/solr/select?q=the+solr&spellcheck=true&wt=json
6. got the desired result, but also the wrong suggestion "thex"

{ "response" : { "docs" : [ {...  "name" : "Solr, thex Enterprise
Search Server", ..  } ],
  "numFound" : 1,
...  },
...
  "spellcheck" : { "suggestions" : [ "the",
  {..."suggestion" : [ "thex" ]  }
] }
}

Sorry for that confusion: The stopfilter refers to the stopwords.txt

Now I'm just talking about the solr example webapp
(apache-solr-3.6.0.tgz/example) which I slightly modified (as
described in the last mail).

In this example solr makes also suggestions for stopwords.
I can't see a mistake in my configuration.

1. The stopfilter refers to the stopwords.txt:


  
  ...

  ...
  
  
  ...

...
  


2. The SpellCheckComponent refers to the field "name":

 name

Now I've found a solution, although I'm not sure, if it's that what
you've meant:

Now I'm using a special fieldType WITHOUT stopwords for the spellcheck field.
So - I think - the SpellCheckComponent doesn't find better matches for
stopwords, because it has indexed the stopwords itself.

Thanks for your help
