Re: querying multiple fields as one
Ken's suggestion to look at dismax is a good one, but I have a question q=type:electronics cat:electronics should do what you want assuming your default operator is OR. Is it failing? Or is the real question how you can do this automatically? I'd expect the ranking to be a bit different, but I'm guessing that's not a big issue Best Erick On Thu, Nov 4, 2010 at 8:21 AM, Tommaso Teofili wrote: > Hi all, > having two fields named 'type' and 'cat' with identical type and options, > but different values recorded, would it be possible to query them as they > were one field? > For instance > q=type:electronics cat:electronics > should return same results as > q=common:electronics > I know I could make it defining a third field 'common' with copyFields from > 'type' and 'cat' to 'common' but this wouldn't be feasible if you've > already > lots of documents in your index and don't want to reindex everything, isn't > it? > Any suggestions? > Thanks in advance, > Tommaso >

The same solrconfig.xml that comes with SOLR has a dismax parser that you can modify to your needs. - Ken Stanley
querying multiple fields as one
Hi all, having two fields named 'type' and 'cat' with identical type and options, but different values recorded, would it be possible to query them as they were one field? For instance q=type:electronics cat:electronics should return same results as q=common:electronics I know I could make it defining a third field 'common' with copyFields from 'type' and 'cat' to 'common' but this wouldn't be feasible if you've already lots of documents in your index and don't want to reindex everything, isn't it? Any suggestions? Thanks in advance, Tommaso
