: I am firing a query having terms- each associated with a boost factor. Some : of the terms are having negative boost also (for negative boost I am using : values between 0 and 1).
except that a value between 0 and 1 isn't really a negative boost -- there's no such thing as a negative boost. what you've got are just boosts with values that happen to be lower then the default value (1.0f). : I am trying to implement a behaviour where the coord factor should only : consider the terms with positive boost. : How should I proceed?. I would like some pointers regarding from where : should I start. you could subclass BooleanQuery/BooleanScorer and change the scoreing function to only compute the coord on the clauses with boosts greater then one. but a simpletr approach that would probably work just as well would be to break your query up into tqo seperate BooleanQueries - one with your "negative" boosts and disableCoord=true, another with your "positive" boosts, disableCoord=false. then put both of those in a new top level BooleanQuery with disableCoord=true. -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
