Rated 5 out of 5 stars

The fact that MAFF is a kind of ZIP provides hidden additional features. For instance, it is possible to make MAFF searchable by content. I succeeded in making MAFF searchable by content at my Vista 64bit. Firstly, I set MAFF searchable by context under indexing settings. Then I installed a ZIP IFilter. Using regedit.exe, I changed registry value of HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.maff\PersistentHandler\OriginalPersistentHandler to the same value as in HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.zip\PersistentHandler\OriginalPersistentHandler

This review is for a previous version of the add-on (0.17.2). 

Thank you for sharing the procedure you followed in configuring MAFF content search on Windows, this is very helpful. A newer version of MAF might configure this feature automatically along with the file associations. If you would like to share additional details, you're welcome on the MAF mailing list.
