I think this needs further explanation. I had never tried the searchHome label before, and I can't get it to work as described here. I tried adding #searchHome="TitleofSomeNote" before and after hitting the Save to Note button on the search UI to no effect - still gets added to the daily note. I know this is likely user error on my end - But if we are trying to make this obvious to new users, that's not working here.
Ah, ok, seems obvious now - of course that label has to be added to the note where you want saved searches to go under, duh. But it isn't clear, I tried several things before it finally hit me! So probably good to clarify that

Also, it might be worth it explaining the labels that already come with a new search:
#searchString="bash script" #keepCurrentHoisting ~ancestor=root
