Some are looking for the greatest gas giant to find the distinction between gas giants and brown dwarfs and some are searching for all types of planets in a star system already known to find the maximum number of planets in one solar system. All of these exoplanet hunters have one thing in common - they all find gas giants more or less by accident while searching for their particular interesting exoplanets. But when they find one of these planets they don't just leave it for good but spend time to find out as much as possible anyway.

Can't say i know this is how it's done for sure, but that's the idea i've always had.
