The one radical change I'd like in the area of adjectives in noun clauses is if more weight were put when the adjectives apply to the appropriate noun. For example, a search for: 'red baseball cap black leather jacket' should find a doc with "the guy wore a red cap, blue jeans, and a leather jacket" before one that says "the guy wore a black cap, leather pants, and a red jacket". The closest I've come at doing this was to use a variety of "phrase slop" boosts simultaneously - so that "red [any_few_words] cap" "baseball cap" "leather jacket", "black [any_few_words] jacket" all add boosts to the score. > > wunder > > On Oct 4, 2010, at 8:38 PM, Otis Gospodnetic wrote: > >> Hi, >> >> If you want "blue" to be used in search, then you should not treat it as a >> stopword. >> >> Re payloads: http://search-lucene.com/?q=payload+score >> and http://search-lucene.com/?q=payload+score&fc_type=wiki (even better, >> look at >> hit #1) >> >> Otis >> ---- >> Sematext :: http://sematext.com/ :: Solr - Lucene - Nutch >> Lucene ecosystem search :: http://search-lucene.com/ >> >> >> >> ----- Original Message ---- >>> From: Hasnain <hasn...@hotmail.com> >>> To: solr-user@lucene.apache.org >>> Sent: Mon, October 4, 2010 9:50:46 AM >>> Subject: Re: Prioritizing advectives in solr search >>> >>> >>> Hi Otis, >>> >>> Thank you for replying, unfortunately Im unable to fully grasp what >>> you are trying to say, can you please elaborate what is payload with >>> adjective terms? >>> >>> also Im using stopwords.txt to stop adjectives, adverbs and verbs, now when >>> I search for "Blue hammers", solr searches for "blue hammers" and "hammers" >>> but not "blue", but the problem here is user can also search for just >>> "Blue", then it wont search for anything... >>> >>> any suggestions on this?? >>> >>> -- >>> View this message in context: >>> http://lucene.472066.n3.nabble.com/Prioritizing-adjectives-in-solr-search-tp1613029p1629725.html >>> >>> Sent from the Solr - User mailing list archive at Nabble.com. >>> > > > >
