4 estimate » 4 estimates, _ estimate, 2 estimate
2f estate » 24 estate, 27 estate, _ estate
21 john » 11 john, 23 john, 25 john
22 john » 23 john
12 john » 11 john
2 john » 3 john, 4 john, 5 john

• If you are trying to use Boolean operators, they must be ALL CAPS: %22orlebar%((((21 john) OR (1 john))) OR (((22 john) OR (((12 john) OR (2 john)))))) %((2f estate) OR (4 estimate))%22.
• Adding a wildcard symbol may retrieve word variants: %22orlebar%((((21 john) or (1 john))) or (((22 john) or (((12 john) or (2 john)))))) %((2f estate) or (4 estimate))%22*.
