The other trick that the relevancy experts know about: you get better top
results using "OR" query of the base terms combined with "OR" of the
proximity phrases of the terms if you are willing to accept that there may
be less-than-desirable results further down the list. Sure, people don't
like seeing the mis-matched results in the list and a larger number of
results, but it's all a tradeoff to assure that the most relevant results
are higher and exact matching is a little looser.

One variant on Upayavira's comment would be to use
the proximity as a boost query. That way all three would
match, but the first two would get higher scores.
Either way should work though.

you might use proximity. "low blood pressure"~6 might match #1 and #2
but not #3.
It says find phrases that require six or less position moves in order to
match my terms as a phrase.
