   It is currently not possible, but would surely be advantageous.

   Current behavior is as follows:

   1. search term gets split on whitespaces
   2. all substrings are interpreted as a regular expression
   3. all regular expressions are used build the database query with $or operation
   4. the query is evaluated against a prebuild "full text search" string

   If you have any ideas for the implementation, especially regarding the user interface, you are welcome to give the implementation a shot or leave a comment. Searching the database for explicit fields is no problem in theory.
