How to find words and phrases as well

[André.Bisseret]

Hi ! and thanks for help,

Every card in my app are including a fld « theText » which displays  
texts.
In a special fld « keyWords » the user can write one or several words 
separated by spaces, say, theKeyWordsList.
A button « search » executes « find words theKeyWordsList in fld « 
theText » such as the list of cards whose text includes all the words 
of theKeyWordsList is displayed to the user in a specific results field.

I would like to be able to find not only words but also phrases. For 
example, the users should be able to enter « user interface » as a 
whole, while now they only can enter the two words « user » and « 
interface ». (not sure I am clear enough ?!).
How to distinguish, for a find command, « user interface » as a phrase 
from « user interface » as two words.
