About This Plugin
SearchWP Boolean Search is an extension for SearchWP that lets visitors refine a search by excluding keywords. They add the "NOT" operator or a hyphen in front of a term, and results containing that term drop out.
It needs no configuration. Boolean search is on as soon as you activate the extension from the SearchWP interface, and it applies to every search on the site. That includes an e-commerce search, where it gives shoppers more targeted results.
