Hi Raakhi,
yes, then the collapse patch works perfectly in our case. If you don't
get the patch applied correctly, try asking directly here:
https://issues.apache.org/jira/browse/SOLR-236
I did the same and got immediately response from Martin & Co or try the
latest patch:
2010-06-17 03:08 PM Martijn van Groningen
Querying is simple:
q=peter&collapse.field=title
and you will get back only one document for the same title containing
'peter' and
additionally the 'similar'/collapse-count for every document:
<lst name="collapse_counts">
<str name="field">title</str>
<lst name="results">
<lst>
<int name="collapseCount">4512</int>
<int name="collapseCount">4010</int>
...
Regards,
Peter.
