Hi Mike,
> - exact match (disabling stemming): Ideally, users need a way of turning > this on or off for terms in their query (e.g. [ =walking running ] would > stem the word running, but not walking). > Correct, there is no way to do this with Solr just by activating/deactivating one parameter. You could implement it very easily by using two fields, one with and one without Stemming, I don't know how this is implemented in Sphynx. > - term quorum: This can be done via the mm parameter, but not as part of > a query. Making it part of the query increases the flexibility of the > parameter, since users can make queries like [ (dog cat kitten)/2 AND goat > ], which could request documents containing two of dog, cat or kitten, as > well as goat. > That's right, this is not a supported syntax. You could investigate nested queries, I think those might help you but I doubt you can expect a user to type those. See http://www.lucidimagination.com/blog/2009/03/31/nested-queries-in-solr/ > - term order: Requesting that one term come before another doesn't seem > to be possible, but can be very useful in some cases. > You may want to investigate Span Queries. http://www.lucidimagination.com/blog/2009/07/18/the-spanquery/ and Solr's support for them. > > These are all possible in the Sphinx search engine, which is what I'm > coming from, and I don't see feature requests for them in Jira. Would it be > worth it to put these in, or is there a reason that Solr/Lucene don't > currently support these functions within queries? > > Thanks, > > Mike >
