"It could weight one search term in a query as being more important or meaningful than another. So, searching on A +B might be highly weighted toward A, whereas searching on A +C might be highly weighted toward C."

This is already in affect on AV. IDF (inverse document frequency) Gives words found on fewer documents in the AV database more pull than common words. This is why I reccomend optimizing for words in your search phrase seperately.
