I see three options:Leave it 'as is' and hope people don't get put off by the occasional result they find strange.We allow users to set a relevancy cut-off themselves.  Each search result gets a score from 0 to 1 (with 1 being very relevant) and every result that matches the search term gets at least 0.0001 and therefore can be shown in the results.  We could give users a 'slider' to allow them to chose what cut-off they want, So some might chose 0.1 while others might chose 0.3.We effectively borrow a concept from PubMed's Clinic...
