You'll need to force a rebuild to pickup any missing properties.
For all of the indexes I have, I assume. Can't this be done for multiple indexes at the same time?
You'll only need to do this once after upgrading to 1335.
After the forced rebuild, maintaining indexed properties in Everything 1335+ should be improved.
Everything 1334a+ will now mark the folder as out of date if you change an indexed property setting.
Very nice! So as long as a folder is not marked an index ALWAYS is up to date? And a folder will not be marked, if a property (of one or more files) is not indexed at all (although bein set)?
This change only applies to offline folders after you have made a change to an index property setting.
Indexed-properties can be out of date if you unplug a device that Everything is currently scanning.
1335 also improves handling of offline volumes when indexing properties.
You might still see one or two files (instead of most files) with out of date properties if you unplug the device while it is being scanned by Everything.
In short, Everything still doesn't like volumes being offline, but detection and handling of offline volumes is improving..
