How to get TermRecognitionHitList from TermbaseRecognitionEngine via FindTerms?

Hi DevTeam,

I'm considering create function to protect terms from source segment before send to MT and upload + replace terms in target after MT.
I found a class TermbaseRecognitionEngine in Sdl.MultiTerm.Client.TerminologySearch.dll with function
public TermRecognitionHitList FindTerms(string text, short termbaseMaxHits, bool includeHomonyms = true, bool allowOverlappingTerms = false)

I didn't see termbaseMaxHits from UI setting what does this mean?
How to get TermbaseRecognitionEngine class, maybe providing local/server Multiterm
