finder - search feature
I would have assumed that when you type in .pdf the finder would have only found files ending in pdf. It doesn't. I get other files ending in other extensions.
Searching for pdf returns files that do not have any characters with the letters pdf as a file name or extension. (I get file names that end in .zip or .css and others.
Searching for *.pdf returns nothing.
I clearly need help understanding how the finder locates files with partial searches.
