yughmoH            include,  cause to be included (v)

(De'vID, from Okrand, 2/17/2018):  To filter (in this sense) is {yughmoH} “include” (that is, “cause to be included”).  So {X neH yughmoH} “filter for X only, include X only".

2. I was not sure if *loch* only works for mathematics and *yugh* only for chemistry. If it is so, how could I say *be a part / member of* and *consist of* in >>Klingon?

I think loch works fine here. We are told that loch is used in mathematics, but we aren't told that loch is only used in mathematics.

I assume the same goes for *yugh*, right? 

Yes, with regards to chemistry. Specifically, Marc Okrand has used yughmoH to refer to computerized information filtering.
