You may find it faster to search each direction as a one-way trip, because if you can find availability for a one-way trip, it can be part of an open-jaw itinerary.
You may also find
www.baredemptionfinder.com a useful tool for a high-level indication (ie which days, with no indication of which flights on each day) of when there might be availability. Once you have that indication, you can then use ba.com in a more focused way to find out which flights might work.
