You simply make use of the OnPrepareSQL event.
You may want to make use of the same routines that the controls use for
parsing and integrating the search criteria. I suggest you trace into the
handling of the SearchBuffer of the data links when IBO is going through the
OnPrepareSQL event processing. This will show you methods and routines you
can take advantage of if need be.

In most cases it is as simple as making controls 'search aware' as I show
the toggle button in the Contact sample application. There is a fair amount
written about making things 'search aware' in the archives too.

Subject: [IBO] How do search at runtime?


> Hi, with IB_Query in search state, I want to fill the fields with

> Assigning with FieldByName('LASTNAME') does not work too, since when
