referenceing/finding word from one documents into another documents and indicating their location

[rok123]

Would greatly appreciate your help. I would like to do the following:

I have two documents summarydoc and detailsdoc, VBA will
1. Search the bold words or phrases (key words) in summarydoc,
2. find their synonyms from the word thesaurus
3. look for the key words and synonyms in the detaildoc
4. Highlight the found key words/synonyms in the detaildoc
5. In the summarydoc by the side of the searched word, indicate the paragraph number of the detaildoc & word/synonyms pair that found
6. Remove the bold formatting of key words from the summarydoc

Following is example of input documents and resulted documents.

Starting documents:
