Spotlight (mac osx) won't search LiBo docs. Any Solution?

Spotlight wil only search based on doc names; not on the contents.
OSX Yosemite 10.10.2
Libo Version:

It is a spotlight problem not LibO. Please look if spotlight has settings which allow odt (and other LibO formats) search.

In spotlight, I can only choose to search generic types of files, e.g. “documents, spreadsheets, applications, etc” but no specific file types. Furthermore I selected to search everything that is listed in the settings. However I found there were some issues before with this phenomenon. See link.

Re-Indexed spotlight and spotlight working perfectly now !!!

Probably a restart would have fixed the issue too ;-))
