Improve search function

I'm a relatively new user of MuseScore and often have to search in the handbook how to do something.

The handbook is certainly useable, and with the help of the table of content, you can, if you are lucky, find what you search for. I'm using MS 4.2.1 for which the handbook is not yet complete so in some cases, you have to go back to the 3.x handbook although I'm not absolutely sure if it's still the same on 4.2.1. This is very time consuming and in many cases unsuccessful because you simply don't know where to search.

Luckily, there is a search function but this is unfortunately not intelligent as you cannot search for an expression, just single words.
If I, for example, would like to search for the expression Select voice, you get hundreds of hits for select and voice as individual words. It doesn't help if you search for "Select voice", SelectANDvoice, 'Select voice' etc because it renders you the hundred of hits or nothing at all.

I think that one of the most important improvement for many users, particularly new users, would be to implement an intelligent search function in the online handbook. I've seen many comments on this forum, which I appreciate a lot, about how to do certain things. In many cases, the answer is, see the handbook and maybe a link.

I've, in my previous life, i.e. before retirement, in space engineering I'v been, among others, responsible for satellite operations manuals. In my last project, BepiColombo, a satellite en route to Mercury, the manual had about 100k pages plus another 1000 or so support documents. As you cannot know where to search for everything, an intelligent search over the complete manual was absolutely necessary and requested by the customer, the European Space Agency (ESA).

It should be noted however, that we had to deliver a stand alone manual. Hence, the search engine had to work locally on every computer where the "document library" was "installed".

After this long rant. Can we get an intelligent search engine?
