The WPFTS Pro version you are using is very outdated. Please consider upgrading to 2.46.x which is the latest. It has a completely new indexing and searching algorithm and it should solve your issue.
Search Results - BOOLEAN Operators and Relevance
Our implementation of WPFTS is configured with the Default Search Logic set to "AND".
I did a search of our website for "2015 Committee", both with and without the quotation marks (the results were the same), and the second and third most relevant results did indeed contain the phrase "2015 Committee"; the second twice and the third once
However, the top result did not. It was a Bibliography for the year 2015, and contained "Committee" nine times, and "2015" 962 times, but in completely different parts of the document.
This feels more like an "OR" result than an "AND" one, but maybe I misunderstand how the "AND" and "OR" operators work?

Yes, the algorithm thinks the number of words here is more important than the exact phrase... Ideally, if we could justify the relative weight for the phrase matches. Currently, it's too low for your case, but I think if we can double it, this could solve the issue.
I think to put this parameter to settings in the near future. Thanks!
