Webglimpse supports boolean-style queries and wildcards, as well as some limited regular expressions. Words separated by spaces are treated as a connected phrase. To signify AND, OR and NOT, use the punctuation symbols ";" (semicolon), "," (comma), "~" (tilde). You may nest expressions using the symbols "{" and "}" (curly braces) to signify parenthesis. You may use the '#' character for wildcard matching.
