Question on Facet counts by grouped results

[Sohail Aboobaker <sa...@gmail.com>]

Hi,

We have an index that contains following fields:

a. Item masterid
b. Item Level 1 Categories (multi-valued field)
c. Item Serial
d. Item description
e. Price.
and some other fields.

I am querying the by using following:

select?q=*:*&group=true&group.field=itemmasterid&group.ngroups=true&facet=true&facet.field=level1categories&group.facet=true

Test index has only 4807 items.

I get perfect counts for groups (total items 4807 and number of groups=1119).
<lst name="itemmasterid">
    <int name="matches">4807</int>
    <int name="ngroups">1119</int>
<arr name="groups">

but in the facet part, I get:
<lst name="facet_counts">
   <lst name="facet_queries"/>
     <lst name="facet_fields">
          <lst name="level1categories">
               <int name="Artists">4761</int>
               <int name="Watches">41</int>
               <int name="Jewelry">5</int>
           </lst>
       </lst>
     <lst name="facet_dates"/>
    <lst name="facet_ranges"/>
  </lst>

*************
By adding &group.facet=true, I was expecting to see counts by group
not by individual items.

What am I doing incorrectly? Or what is the way to achieve facet
counts by groups.

Thank you for your help.

Regards,
Sohail

Thanks Erick,

It works perfectly now. My purpose was to just test the group facet count
feature and that works as expected. Can't wait for this release to be out :)

Yes, stopwords_en.txt. Or go into your schema file and find the
usages of stopwords_en.txt and change it to a  stopwords file
in your setup.

Best

I had copied the full example directory. After copying, I had replaced
schema.xml from my old 3.5 schema.xml and I faced this error. After Eric's
email, I copied stopwords_en.txt into conf directory of my copy. It works
fine after that.

After seeing your email, it seems that the better approach would be to add
lang/ infront of the stopwords_en references in my copied schema.xml
because lang/ did not exist in the 3.5 directories.

: the schema.xml. It worked fine but in 4.0, I did the same thing (make
: a copy of example) but when I change the schema, I get following:
: 
: Apr 26, 2012 5:04:12 PM org.apache.solr.common.SolrException log
: SEVERE: null:java.lang.RuntimeException: Can't find resource
: 'stopwords_en.txt' in classpath or 'solr/./conf/',

you'll have to be more specific about what changes you made.

The current trunk example contains a "lang/stopwords_en.txt" file which is 
refrenced from the example schema.xml -- so depending on what changes 
you made, and wether or nor you copied the entire example/solr 
directory, you may or may not get errors...


hossman@bester:~/lucene/dev/solr/example$ find -name stopwords_en.txt
./solr/conf/lang/stopwords_en.txt
hossman@bester:~/lucene/dev/solr/example$ grep stopwords_en.txt solr/conf/schema.xml 
         (lang/stopwords_en.txt), down cases, protects words from protwords.txt, and
                words="lang/stopwords_en.txt"
                words="lang/stopwords_en.txt"
                words="lang/stopwords_en.txt"
                words="lang/stopwords_en.txt"
        <filter class="solr.StopFilterFactory" ignoreCase="true" words="lang/stopwords_en.txt"/>

Hi,

I am trying nightly build for solr 4.0. I downloaded the build and am
able to start it. In 3.x, I copied the example directory and updated
the schema.xml. It worked fine but in 4.0, I did the same thing (make
a copy of example) but when I change the schema, I get following:

Apr 26, 2012 5:04:12 PM org.apache.solr.common.SolrException log
SEVERE: null:java.lang.RuntimeException: Can't find resource
'stopwords_en.txt' in classpath or 'solr/./conf/',
cwd=/apps/servers/apache-solr-4.0-2012-04-26_08-10-58/apache-solr-4.0-2012-04-26_08-10-58/trusted

Do i need to copy some other files in my copied directory as well?

We are hoping this year. There will be a series of alphas and betas that should start within a month or few.

Never mind, I did not notice that this is coming in Solr 4.0. Any
ideas on when Solr 4.0 will be out?
