Hi,
I have a problem with Solr and Faceting and wondering if anyone knows of the fix. I have a work around for it at the minute, however i really want to work out why my query isn't working.
Here is my Schema, simplified to make it easier to follow:
<fields>
<field name="uniqueid" type="string" indexed="true" required="true"/>
<!-- Indexed and Stored Field --->
<field name="recordtype" type="text" indexed="true" stored="true"/>
<!-- Facet Version of fields -->
<field name="frecordtype" type="string" indexed="true" stored="false"/>
</fields>
<!-- Copy fields for facet searches -->
<copyField source="recordtype" dest="frecordtype"/>
As you can see I have a case insensitive field called recordtype and it's copied to a case sensitive field frecordtype which does not tokenize the text. This is because solr returns the indexed value rather than the stored value in the faceting results.
When i try the following query:
http://localhost:8080
/solr
/select
?version=2.2
&facet.field=%7b!ex%3dfrecordtype%7dfrecordtype
&facet=on
&fq=%7b!tag%3dfrecordtype%7dfrecordtype%3aLarge%20Record
&f1=*%2cscore
&rows=20
&start=0
&qt=standard
&q=text%3a%25
I don't get any results, however the facteting still shows there is 1 record.
<result name="response" numFound="0" start="0" />
<lst name="facet_counts">
<lst name="facet_queries" />
<lst name="facet_fields">
<lst name="frecordtype">
<int name="Large Record">1</int>
<int name="Small Record">12</int>
<int name="Other">1</int>
</lst>
</lst>
<lst name="facet_dates" />
</lst>
However if i change the fitler query (line 7 only) to be on the "recordtype" insted of frecordtype:
http://localhost:8080
/solr
/select
?version=2.2
&facet.field=%7b!ex%3dfrecordtype%7dfrecordtype
&facet=on
&fq=%7b!tag%3dfrecordtype%7drecordtype%3aLarge%20Record
&f1=*%2cscore
&rows=20
&start=0
&qt=standard
&q=text%3a%25
I get the 1 result back that i want.
<result name="response" numFound="1" start="0" />
<lst name="facet_counts">
<lst name="facet_queries" />
<lst name="facet_fields">
<lst name="frecordtype">
<int name="Large Record">1</int>
<int name="Small Record">12</int>
<int name="Other">1</int>
</lst>
</lst>
<lst name="facet_dates" />
</lst>
So my question is, is there something i need to do in order to get the first version of the query to return the results i want? Perhaps it's something to do with URL Encoding or something? Any hints from some solr guru's or otherwise would be very grateful.
NOTE: This isn't necessary a faceting question as the faceting is actually working. It's more a query question in that I can't perform a query on a "string" field, even though the case and spacing is exactly the same as the indexed version.
EDIT: For more information on faceting you can check out these blog post's on it:
