Thanks for the bug report.
The url-associated iFilter treats URL files as having no content. (just a bunch of properties)
Please try the following search:
voidtools.url utf8content:voidtools.com
utf8content: will treat the .url file content as UTF-8.
While .URL files are technically not UTF-8, they are usually ASCII only (a subset of UTF-8)
Everything 1.5 has a text-plain-content: search function.
text-plain-content: will auto detect the correct text encoding.
I have also added .url files to the
text/plain list for the next Everything 1.5 alpha update.
Extensions is this list are always treated as text/plain.
Everything 1.5 has the URL property which can be searched with the url: search function:
ext:url url:voidtools.com
