Question about community level

[bdytx5]

How do we choose a community level given a query? Is this something that we need to experiment with manually, and basically predict the best community level?

Yes. You can select a community level by hand and pass it in as an arg to the query API for global search. We generally tend to start with level 2. The deeper you go (higher number), the more relevant answers tend to be, but at increased time and cost.

We have also added a param to allow the system to dynamically select communities based on a relevance test. This generally saves quite a bit of time and cost, with equivalent quality. Here is a blog post describing the technique: https://www.microsoft.com/en-us/research/blog/graphrag-improving-global-search-via-dynamic-community-selection/
