My search did multi phrase search since 1999.
It has a max of 6 phrase / mini-phrase search keys..
If any don't exist then the next info is searched...
Wow does it work great for long detailed file names...
i have a recent video on youtube.. called
"squirrel at cabin green mountain road 20190329123657"
After a quick catalog function...
I can instantly search and play that clip
by entering: the / is separator
" road/ gre/abin / squ"
or
" roa/ 201903/irrel"
the thing is I don't need to know the name of a long file to find it..
