It will open the file, read the content, does a strpos() on the search
term and add <span class="found">...</span> around the found word. You
may also need to add the "found" CSS rule like this:

.found {
  background-color: #ff0;
}

If you want to keep the URL "downhole-measurements.html?find=able" you
can also do this with a script in the document itself which takes the
URL (window.location.href), extracts the "find" parameter and calls
either window.find() or walks the DOM tree to add a <span
class="found">...</span> around the search hits - but in any case you
need *code* to do the finding. There is no solution which just works by
adding something to the URL.
