That is a much clearer explanation of your requirements. You are in the domain of semantic analysis. Since you started in the Atom discussion forum I assume that you would like to see this feature in an Atom package. There is a basic word count facility if you search in Packages …
although I have not used these. For advanced text analysis I would look at R packages for text analysis. An R script might be written to run through your list of 2k nouns and run a parallel search. There is an Atom package R-exec which runs R scripts. And R offers a rich source of text analysis.
Returning to the earlier TextSTAT tool I suggested this does not offer multiple word searches which is what you need.
I refer now to another advanced tool AntConc where you can apply a long list of words and you might learn much from initial use of this tool then perhaps write an R script which you can run in Atom using
