Dear corpora members,

I'm trying to find out more about the matching algorithms that UMLS UTS uses for searching in the database. They are the following but I couldn't really get to some detailed explanation what they stand for. Is anyone aware of these types?

Word, Approximate match Exact match Normalized string Normalized word Right truncation Left truncation

Thanks! Ivelina
