This addresses an issue reported on the forum where searching for a keyword
in FAQ search brings back more results than it should. This is due to the
format of the query selecting the results, essentially, the `WHERE NOT`
statement is not properly formatted so the `OR` statements take precedence
over the `WHERE NOT` causing non-public results to be shown to the client.
The `WHERE NOT` statement contains the bit to select from only public faqs
and since the `OR` takes precedence it will return the non-public results
too.
