The question is a bit abstract.

If a Topic version holds an @ishcondition looking  like "COOLING=WATER AND ENGINETYPE=ELECTRIC"

• So COOLING is a condition name, WATER is a condition value. Same for ENGINETYPE and in ELECTRIC.
• Per Topic, Map, Library Topic the system collects ithe individual conditions. So field FISHCONDITIONS contains two entries: COOLING:WATER and ENGINETYPE:ELECTRIC

In turn a Publication Version holds a Context. These are condition values that could make ishconditions valid/include or invalid/hide.

• So if FISHCONTEXT holds COOLING=AIR and ENGINETYPE=ELECTRIC, then the above condition will not become valid (as it cannot make the COOLING=WATER part true).

So trying to map your question to product terminology. 

• When referring to "a list of publications which have conditions set on them".... You are looking for Publication Versions that hold a context that makes ishconditions become true when published. Then Pubblication Version FISHCONTEXT is your target.
• When referring to "contain content with conditions".... Does this means Topic, Maps, Library Topics that are used within a Publication Version (or not?) that use a particular boolean logic condition? You can try over FISHCONDITIONS field or try the Search API with the advanced attribute syntax. 

Best wishes,
Dave
