this name still feels ambiguous to me, what is the LIKE comparison doing again? is it a regex match?

Yes, it is just doing something like column LIKE '%pattern%'.

Personally I think this function should be bounded with datatypes. Unfortunately I didn't find any place to insert the allowed datatypes with those functions. Do you have better idea?

We also explored some new ways to implement self-query retriever with openai's function call. We found pretrained LLMs are good SQL translator so it is probably a good new to SQL based vector databases.

Sorry I probably misunderstand the issue. Do you mean the LIKE is ambiguous? Perhaps SUBSTRING_MATCH would be a better fit?
