Release Date: May 16, 2018 | SearchWP – Boolean Search implements support for boolean operators in searches (e.g. terms preceeded with a direct hyphen (no white space) or <code>NOT</code>)
Boolean Search requires no configuration. It adds support for excluding results based on keyword. For instance, if the search query is “cats -dogs -birds” only entries with “cats” and without both “dogs” and “birds” will be included.
