Search for multiple words

Hello,

I´m brandnew to RNB but can´t find out yet how todo this:

Is it possible to do a search with multiple words, so RNB
only shows me all the records containing all the words
/ fragment from words ?

e.g. can I enter "red" and "blu" in the seaching field an RNB
shows my the all the records which contain both "red" and "blue"
or "deep-red" and "blues" ?

Or do I simply has to enter something like "red AND blu"
on the searchline ?

Regards,

Luzie
