Unfortunately there isn't currently a general "contains" operator.
However, since what you want to do is a "starts with", and you're
hard-wiring the comparisons, it is possible to fudge it with the current
Greenstone operators:


Katherine is going to add "starts with" and "ends with" operators so
things like this are easier to do in the future.

All the best,
