Perhaps you should try some spelling variations:
"anti-provers" » "anti-proverbs", "anti-proves", "anti-providers", "anti-provens", "anti-proveds", "anti-provess"
"anti-prover" » "anti-proven", "anti-proved", "anti-proves"
"anti-approved" » "anti-improved"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ("anti-provers" OR ("anti-prover" OR "anti-approved")).
• Removing quotes may allow a broader search: ( anti-provers or ( anti-prover or anti-approved )).
• Adding a wildcard symbol may retrieve word variants: ("anti-provers" or ("anti-prover" or "anti-approved"))*.
