Bug Description

I opened this pdf page https://www.asee.org/papers-and-publications/publications/college-profiles/2015-graduate-engineering-degrees.pdf

and for example try to find by typing "computer engineering", it shows 2 or 4 matches where there are around 25 or more instances of this phrase.

Definitely a bug in the pdf viewer. Tried to reproduce myself.

Even if you don't want to scan the whole pdf for performance constraints you shouldn't display wrong match count. Count all if it won't crash the browser.
