Field Collapse question

Is there a way to configure the Field Collapse functionality to not collapse Null fields? I want to collapse on a field that a certain percentage of documents in my index have...but not all of them. If they don't have the field I want it to be treated uncollapsed. Is there a setting to do this? -

Query modification

If I wanted to intercept a query and turn q=romantic italian restaurant in seattle into q=romantic tag:restaurant city:seattle cuisine:italian would I subclass QueryComponent, modify the query, and pass it to super? Or is there a standard way already to do this? What about changing it to

Re: Field Collapse question

I wanted to extend my question some. My original question about collapsing null fields is still open, but in trying to research elsewhere I see a lot of angst about the Field Collapse functionality in general. Can anyone summarize what the current state of affairs is with it? I'm on Solr 1.4, ju

Re: Query modification

So QueryComponent is the place to do this? Are query analyzers already done? Would I have access to stems, synonyms, tokens, etc of the query? -- View this message in context: http://lucene.472066.n3.nabble.com/Query-modification-tp939584p940941.html Sent from the Solr - User mailing list archiv

Re: index format error because disk full

Re: How do I get the matched terms of my query?

if you want only documents that have both values then make your q q=content:videos+AND+content:songs If you want the more open query, but to be able to tell which docs have videos, which have songs and which have both...then I'm not sure. Using debugQuery=on might help with your understanding,

Re: Score boosting

Sounds like you want Payloads. I don't think you can guarantee a position, but you can boost relative to others. You can give one author/book a boost of 0 for the phrase Cooking, and another author/book a boost of .5 and yet another a boost of 1.0. For searches that include the phrase Cooking, the

Re: Database connections during data import

Gora, Our environment, currently under development, is very nearly the exact same thing as yours. My DB is currently only about 10GB, but likely to grow. We also use Solr as primary repository (store all fields there), but use the DB as a back up when Full Import is needed. Delta imports aren't th
