#495: WebSearch: improve/fix "NOT" operator

When a query includes a "NOT" expression for which there is no result, the
search engine returns no result, whatever the rest of the query matches.
For example the following query does not return any result on the Atlantis
Demo Site:
{{{muon -foo}}}
though "muon" matches some documents (and "foo" does not).
One could expect to still get the documents matching "muon".
