I'm sure this is very simple, but I can't figure out how to do it. I want to combine len: >x when searching for a type of file (e.g. *.pdf) or other named file.
Help section says "Simply prefix "len:" to the search term in the name field." But "search term" here is simply the number for length--I think.

Something like this?

I hadn't done this before so tried it out. For folks who don't (but should! ) normally think of filenames as including path, use "lent" i.e.

Note that the initial colon is the Boolean marker. The second term needs a field prefix too if it is a different field from the first one. So it should look like this:

Great. Thank you. For beginnners like me a help section of vast size is needed for the wonderful power of XYplorer. But the Forum serves for that. Then again, could there perhaps be a short bibliography for the most necessary basics?
