Regarding the backend, have a look at libs/database/imagequerybuilder.cpp
There is already "pageorientation" and "pixels" implemented which provide 
similar queries.

For the UI, you need to build the basic UI in 
utilities/searchwindow/searchfields.cpp. There is already something for 
pageorientation, nothing for pixels.
If you want the UI to appear in the search window, you need to add in in 
searchgroup.cpp.
