How to search Writer document for list of words from Calc?

I’m a content writer and often need to search my Writer documents for lots of keywords to make sure I have included them all. If I have a list of them in a Calc spreadsheet, is there a way to search the document for all of them, or one by one, automatically? Some of them are a phrase of two or three words, I assume this might cause problems.

I’m currently doing it manually copying and pasting into the search bar, but when you have a list of 50 keywords and lots of pages, it takes quite a while.
