I had trouble using double quotes in my search...
... or, more precisely, it was when I switched OUT of Google to another search application that caused the problems.
I'd searched for a particular lyric (one I've used before) "When Venus the goddess of beauty and love." In Google, this works perfectly--I can find the music easily.
But then, once I'd switched back to my laptop I used Apple's Spotlight search utility to find a copy of the song lyrics that I knew I had on my hard drive somewhere.
I tried and tried.. and failed. Trust me, I'm 100% sure I've got a copy--the question is Why can't I find them?
I thought that perhaps the index for the Spotlight system was broken, but no--after a few moments I figured out that it was user error. I'd been entering the same query complete with the quote marks:
[ "when Venus the goddess of beauty and love" ]
And THAT wasn't working.
Luckily, I figured out quickly that Spotlight searches for whatever you enter, including the quote marks. So, to make it work, I had to NOT use the double quotes!
It means that I have to know the particular details of each search / find engine I use! It's not an onerous burden, but you need to know, if you're going to use these tools well.
This impressed me so much that I made a short video about it... Here you go...
Hope you find this one useful!
