lucene question( summary of values by field )
Hi !
I make a search and get the hits. this hits have lucene records say r1,
.... rn. eache record has
the fields f1 , f2 ... fn .
I need to get a sumary of field values ( like those ebay , and shopping.com
do )
for example :
values for field f1 -> A :50 records
B :60 records
Others : 30 records
(asuming the search produced 140 lucene documents. )
I really would apreciate if anybody knows how can I program that
functionallity. I did it using a 'for' loop trough all the records , but
it gets very slow when the amount of records is so large.
Thank in advance for your ideas.

For counts per facet you probably need to use Solr Faceted Browsing
- http://wiki.apache.org/solr/SolrFacetingOverview
or DB-Lucene integration
- https://issues.apache.org/jira/browse/LUCENE-724
