eZ Tika is of importance in general, but if your eZ Publish site has a lot of binary files ("attachments") or is geared towards DMS cpabilities, eZ Tika is a must! It is capable of converting any modern "office" file type for subsequent indexing, inclusing the latest MS and Open Office file types.

There is one caveat left for general use: indexing of pdf files with asian and sometimes cyrillic characters. This is best done using xpdf. For the latter though, eZ Tika provides a dedicated wrapper script and settings file you can use almost out of the box.
