[req] Show an error if the path is not indexed.

[DPlFnAz5J91kerf]

"es -path . asdf" did not work on the FAT32 disk. I did not immediately understand why :-D

es is pretty dumb when it handles -path, it simply expands the path and passes the expanded path in your search to Everything.

For example,

. => C:\Program Files\ES

ES will pass the search "C:\Program Files\ES" to Everything.
ES will not know if the path exists or not.

I have put on my TODO list: ES -path should do a path lookup and throw an error if it doesn't exist.
