c.env.AI.autorag('my-rag-name').aiSearch() to ask it basically "give me the correct version of the given name". Hoping it would fix the spelling of "Suma Covjek" to "Šuma Čovjek", as listed in one of the files. But results are underwhelming. When I looked at the AI Gateway and what the aiSearch() used for the default system message, I see "...no relevant documents were retrieved for the user's query...". For each and all of them. If I do a search in the playground it would sometimes return a file, but often not the right or relevant one, even if the exact correct spelling is given. What am I missing? How come aiSearch() would not find my content?
