I created something similar a while back, what I did was create a class that was basically a container with:

- A dropdown list for the operators
- A textbox to enter the search value
- A property to indicate the data type for the value
- A property to indicate the name of the field to be searched
- A method that returned the search expression as a string, as in:

ClientName = "PEDRO SILVA"

There was a method in the search form that looped through the objects of this class calling that method and creating a compound search expression.

Once I had the resulting expression I used macro expansion to execute the query, I hope I was clear enough.
