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.

Hi, I am new here and I came because of this. I watched videos on youtube but nothing is working. My table consists of types of vehicles, their prices, the colour and a few other things. Now the problem is that when I ask my bot to provide a list of grey cars available, it can. But when I ask it to provide a list of vehciles that fall under a particular amount, it cannot. What do I do?
