There was a known deficiency in one of the zebra configuration files that caused the symptoms you report.  If your version is older than the July 12th patch, please update your file:
etc/zebradb/ccl.properties

The git version is here:

I have a very basic problem with my Koha 3 test installation.

If I use the "Limit type to" selection, my search does not show anything.
My Items are set as "Books, Booklets, Workbooks", but if I set the "Books,
Booklets, Workbooks" checkbox, I get "No results found".
If I unset the checkbox, it finds my search.

Is this a known issue?

Your help will be appreciated.
