What I like about fuzzy search is that if I search something like 'Constant Remembrance' which is a spiritual concept but it doesn't exist in those exact words in the Gita, fuzzy search comes up with a quote quite close to the concept simply because it is fuzzy. How would full text search work? Would it come up with zero results if the search was not precise?
Exactly. That's how it should work. I searched "love" and got passages "Lord Krishna [...] grieve" which the search included because of LO (from LOrd) and VE (from grieVE) - no mention at all of "love," so not what I was looking for. Just go with standard search.
