I have a field called job title and I want to search records based on this field. For example I am trying to search for CTO. The problem is when I do a searching asking for records those job title "contains" "CTO", I also find a lot of records those job title is "director of ...".

What I would like to do is to search this field doing something like this:

- contains "cto"

- not contains "director"

Any way to do that?

Thanks
