: 1. Can I do away with index-time boosting for fields & tweak : query-time boosting for them ? I understand that doc level boosting is : very useful while indexing. : But for fields, both index-boost & query-boost are mutiples which lead : to the score, so would it be safe to say that I can replace the : index-time boost with query-time boosting. This allows me a lot of : freedom to test different values without re-indexing which takes me : about 6 hours.
it depends on your goal. index time field boosts are a way to express things like "this documents title is worth twice as much as the title of most documents" query time boosts are a way to express "i care about matches on this clause of my query twice as much as i do about matches to other clauses of my query. : 2. When searching through the archive I had read a post by you, saying : its possible to give exact matches much higher weightage by indexing : the START & END : from : http://www.nabble.com/What-are-norms--tf1919250.html#a5335856 the context was that even if you turn off field norms you can still some score benefits/restrictions of matches on shorter fields vs longer fields by indexing marker tokens (things you wouldn't expect to be regular tokens; i used START and END just for convinience) at the begining and ending of hte field, and then including them in your phrase or span near query with lots of slop ... so a values like... Duke Ellington The Duke Ellington Band get indexed as the tokens... {START} {duke} {ellington} {END} {START} {the} {duke} {ellington} {band} {END} ...when doing a sloppy phrase or span near search for [ START, duke, ellington, END ] both of those values will match, but the first will have a higher score. -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
