1. What human languages does it support.

2. In these human languages how does stemming and decompounding work in your implementation.

3. how is word importance determined in your index - TF-IDF? other algorithm? Are least important words automatically dropped from queries?

4. Do you have ability to rank on both the stemmed/decompounded query/results and exact matches? So something like raw field access.

5. Can I create my own semantics - I remember seeing a post on here recently where someone had created a search engine (in Rust I think) that was faster than ElasticSearch but from what I could see you couldn't create your own field names so you were stuck searching in title, description, body, creationDate and a couple other fields which really decreases the usefulness.

I mean these are the things that right away spring to mind to ask about when someone tells me they have a new search engine, and when they show me look at my speed benchmarks I'm thinking "what am I supposed to do with this?"

on edit: formatting

on second edit: So I guess as in most things I am interested in how the product actually fulfills what should be its primary functionality, so how does the search engine function as a search engine, I suppose my questions could be answered with quick - our search engine has feature parity with ElasticSearch / Solr where features A, B, and C are concerned - features D and E will be supported in the future.
