Is your feature request related to a problem or challenge? Please describe what you are trying to do.

Part of #5374
We haven't support them yet. In DataFusion query like below, we will need to call min_string_view(), which is not yet implemented

SELECT "SearchPhrase", MIN("URL"), COUNT(*) AS c FROM hits WHERE "URL" LIKE '%google%' AND "SearchPhrase" <> '' GROUP BY "SearchPhrase" ORDER BY c DESC LIMIT 10;
