Hello everyone, I need some input to understand how feasible is a personal project I wanted to start. I have 10 years worth of personal journaling and wanted to index them and query upon them. The data is plain text (but I can structure it somehow) in a couple of files (each by journal category). I've tried a TreeIndex, but due to a coding mistake after generating it I didn't manage to save it and lost it, it costed me around 14€ of API tokens (was 250~ chunks of data). And I also noticed that querying it was really expensive... does the cost of a query scale app rather quickly depending on the size of the index?
