Re: Stemmer vs. exact match
Hi, I have the same reflexion actually. If you add an another field for exact search, and the end cannot type a search like : "convertible" +house Because in this sample, for 'convertible' the user want an exact search but not for 'house'. And I don't want to develop an new parser for query. I think, the solution is to add something in the stemmer analyser to store exact word too, and a parser that don't stem expression in quote.

modify SOLR scoring
Hi everybody, I'm using SOLR with a schema (for example) like this: parutiondate, date, indexed, not stored fulltext, stemmed, indexed, not stored I know it's possible to order by a field or more, but I want to order by score and modify the "scrore"" formula. I'll want keep the SOLR score but add a new parameter in the formula to boost the score of the most recent document. What is the best way to do this ? Thanks.
