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.

Highlight question
Hi everybody, I have an schema seems like this in SOLR: title, type:string , indexed not stored body, type:string, stemmed, indexed not stored xhtml, type:string, not indexed, stored When user make an search on field title, body or both, I want to highlight the match string in the xhtml field only. How I can do this ?

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.
