Bot seems to reference some of the prices from the table but only when the text is an exact match - how can I make it use synonyms

I came here to discord because my tables dont seem to work as a KB.

seems very inconsistent compared to unstructured data in a text document

I am thinking that maybe one has to use AI to translate what the user asks for so that it matches the headers perfectly. To add complexity the column may be stored in English but then the user asks in another language.
