Hi everyone, I'm building a search feature to search through a list of suppliers using the keywords in their categories. I've implemented hybrid search(keyword and semantic search) but I'm wondering whether implementing synonyms for the keywords is still necesssary? I found the semantic search is able to cover some cases from my test but would like to know what's the general industry approach. For example, if a user searches for

footwear

and I have

shoes

in one of the categories, it's returned thanks to the semantic search. Is it necessary to add synonyms?
