Is there a Browser Add on Or Application That Lets You Perform Terms?

Is there a browser add-on or application that lets you perform "terms and connectors" searches within any web page or PDF that has been OCR'd?

According to Statcounter, that would be the Edge browser which has a mere market share of 4% as of November 2018. Source. Desktop Browser Market Share Worldwide | StatCounter Global Stats Edge was DOA because it not only launched with Windows 10, thus limiting its use but it also shipped with incomplete or missing features. The initial version had no extensions, had limited tab management and suffered from performance issues, crashes and instability. Microsoft did manage to add functionality with each Windows 10 feature release but the browser never took off and most users simply ignored it, just like t always ignored Internet Explorer which already had a bad reputation. In terms of total market share (desktop and mobile), the least used browser is the old and unmatained Android AOSP browser which sits at 1.72%. It used to be the default browser until 2012–2013 when it was replaced by Google Chrome on all Android smartphones.
