Hey G's, how can we make a chatbot recognize synonyms and grammar errors? For example, I've uploaded PDF files to knowledge base and let's say there is a paragraph in a PDF named "Content Ideas", and if someone types "Give me 5 post ideas" or " Give me 5 Cntent ideas", it doesn't work. I know that there is a option to add manually synonyms, but I have a tons of files and It would be extremely time consuming for me to add manually synonyms to all paragraphs.
