can you use facet search?
facet=truefacet.field=order_nofq=order_no:(1234 OR 5678 OR
...)fq=artist:Pink Floyd

Hi all-
I have a problem that I'm not sure how it can be (if it can be) solved in
Solr. I am using Solr 3.2 with patch 2524 installed to provide grouping. I
need to return the count of unique records that match a particular query.
For an example of what I'm talking about, imagine I have an index of music
CD orders, created from a SQL database using the DataImportHandler. It's
possible that the person ordered multiple records by the same artist (e.g.
order #1234 contains Pink Floyd Wish You Were, Pink Floyd Meddle, Pink
Floyd Obscured by Clouds). One of the fields indexed and stored fields in
the document is Artist. If I do a search for Pink Floyd, using the order
above, I'd get three documents, all with the same order number, for each of
the Pink Floyd records. What I'd like to find out is how many unique orders
have Pink Floyd across the entire index. The index has millions of
documents.
I have been trying to see if the result grouping functionality provided by
patch 2524 will help, but while it does collapse the query above into one
document, the matches field is still the same as without the grouping (which
I guess makes sense insofar as it is still reporting the number of documents
it found for the query). I have also thought a subquery in my
DataImportHandler might work, though I'm not sure how I'd structure it.
Thanks for any guidance on how to solve this problem; I know Solr isn't
meant to be a data-mining tool and I'm guessing I'm skating perilously close
to using it for that purpose, but anything I can do to take load from the
actual database is considered a Good Thing by all concerned.
