Good news. Now searching will make more sense
If only visio ifilter worked…
Visio Search is actually Possible, yet- not Enabled by default.
you should activate it using the Microsft’s Instructions Placed at the bottom of the MS’s Download Page. There are instructions about enabling office-search-server to search through all sort of files, the v** are to be enabled using a small & easy registry edit (adding 1-2 keys with a long “{.some long number….}” in it, the index service should include the office v** files next time the cache index will be refreshed, (can be done manually).
hope that helps.. :)
