(sorry for cross postings - I think this is important information to disseminate) Executive Summary: you probably need to increase your query slop. A lot. We recently had a feedback ticket that a title search with a hyphen wasn't working properly. This is especially curious because we solved a bunch of problems with hyphen searching AND WROTE TESTS in the process, and all the existing hyphen tests pass. Tests like "hyphens with no spaces before or after, 3 significant terms, 2 stopwords" pass. Our metadata contains: record A with title: Red-rose chain. record B with title: Prisoner in a red-rose chain. A title search: prisoner in a red-rose chain returns no results Further exploration (the following are all title searches): red-rose chain ==> record A only "red rose" chain ==> record A only "red rose chain" ==> record A only "red-rose chain" ==> record A only red rose chain ==> records A and B red "rose chain" ==> records A and B (!!)
