[Feature Request] Improve search algorithm to display results with closest match

### What

Requested in 5318888-zd-woothemes.

> Could the develops please make it so the search favors the
order of the words you type into the search box - even more so if they
appear in the title?

### Why

> For example, if I search for song lyrics and type "when will", the
search currently puts other notes at the top of the results list. Some
notes I search for are buried way down the results list (not visible) so
I have to type more and more words to bring them near the top of the
list.

There's a screenshot attached to the ticket. Not sharing the screenshot here because it may contain private notes.

### How

> So, could it be made so that a match of an exact string of words will
cause any exact matches to appear at the top of the search results?

The issue names no implementation files or tests; start by locating the search algorithm and its result-ranking entry point in the TypeScript application. Reproduce the example query “when will” and compare the current ordering with the requested behavior, then add coverage showing exact word-order and title matches rank above less-relevant notes.
