Adding synonyms to FAQs (data store)?

What are some good ways to add synonyms of questions in data store FAQs, so that a question can be asked multiple ways and still match? (e.g. Not just “What’s the price of X?“ but also “How much for X?“ and “X cost“)

Here are some options I’ve considered, welcoming input on best practice:

  • In the FAQ CSV, make a new row for each variant/synonym of a question, multiple rows all with the same answer
  • In the FAQ CSV, add the multiple forms of the question to the “question” column, separated by semicolons
  • I’ve wondered if there’s a way to edit the data store/add synonyms in Vertex or something

What would you all recommend?

Thanks, Ahn
