Presently you cannot restrict a Web2 search to a particular folder or path. I have mentioned this to SOLIDWORKS but am not certain that an enhancement request was created to add this capability.
That's actually a separate issue. My problem is I can't search for strings contained in a folder name. For example, let's say I had a folder structure:
C:\PDMVault\Legacy PDF Files\Projects\100000\1000050\ACME Thingamajig\
And under that folder are PDF files like, "Part1.pdf", "Part2.pdf", etc. If my user doesn't know where to drill down to find the "ACME Thingamajig" folder I want them to be able to search using the terms "ACME", "Thingamajig", or "ACME Thingamajig". This currently doesn't work for me. I cannot search by strings in a folder name.
