The mandatory part +(DEF GHI) selects documents with either term and scores higher if both terms are present. The sloppy phrase query part "DEF GHI"~10^5 is optional and only contributes to the score when both terms appear near each other (and scores higher the closer together they are). -Yonik >> Solr's dismax parser can generate queries that do most of >> this... it's a combination of term queries and sloppy phrase queries. >> >> Simplest example: >> +(DEF GHI) "DEF GHI"~10^5 >> >> The only thing that it doesn't work for is the terms out of >> order (they will still be matched).
