My experience with Chrome's text search functionality hasn't been ideal. It can act up if there's additional code on the page, or if the code has been tampered with. For example, if you go to a site on your phone and it has this under the URL field, text search won't work:
That bar indicates that the site is using Google's Accelerated Mobile Page (AMP) Viewer, which strips the code to makes the page load faster, but messes with the search function. You can turn the AMP viewer off, but you'll see a difference in page-loading time.
Firefox had the same issue, although it didn't have some of the other glitches I've noticed with Chrome, e.g. auto-returning to the first result when you try to click-through to the second or third results.
Chrome was the only one of the three browsers to put its results at the very top, the way browsers do on your desktop, but that's fairly irrelevant when you have a 1,000-word article and a question that can be answered with one line of text.
