How to boost exact match score in text search

I have a simple text search query: { $text: { $search: initialParams.search, $caseSensitive: false } }

It returns results with a text match accuracy score, however, I found that many exact matches have much lower scores than I would like. This is especially true for multi-word phrases.

I tried to understand how I could boost exact matches to get a higher score, but I couldn’t figure it out from previous forum discussions.

Some help would be amazing!
