Adding Word's search option service

Question

I have defined my own dictionary of legal terms.

I would like to display the dictionary I have created in the form of a dictionary in the research window of MS Word.

That is, I want to add the dictionary I created to related books in the study options.

The currently installed dictionary is stored in C:\Program Files\Microsoft Office\Office16\PROOF in the file format MSGR8EN.lex.

I would like to change my dictionary to a dictionary file (lex file) and add related books in the research options, but I was told that language packs and proofing tools cannot be developed.

So, can we implement Query Web Service and add research option service?

The query web service format is

This will be https://Server_Name/[sites/][Site_Name/]_vti_bin/search.asmx.

Can translation and dictionary functions be added to the research option service using Microsoft sharepoint server?
