Obsidian already has decent and fast search capabilities, and there are people asking for even more granular search option. But what about natural language search? How much more confident would you be in retrieving relevant notes from the past if you had google to search your notes for you?
I think this would actually change not only my behaviour in writing notes — I would probably write more freely and naturally — but also my emotional state as I write; I would be less anxious about remembering all the right tags and links in the moment and more confident that I will be able to find this note later via search.
I just released Khoj for Obsidian. It allows you to use natural language to search through your markdown notes. The search is incremental, so you can see results as you type. Let me know if that satisfies your use case?
