I'm trying to index a taxonomy using GPTVectorStoreIndex. I have build a bunch of documents containing only one line each, like:

Doc1: The name of group 00.01 is appliances.
Doc2: The name of group 00.03 is housing.
Doc1: The name of group 02.02 is animals.

From this I would like to be able to ask: What is the name of group 00.01.

My issue is that for some numbers it works and with others I gpt just answers it can find anything. It seems kind of random. Is this not supposed work?

I have also tried to have everything in one document with one line per group. But again results are a bit random hit or miss.
