Since multiple corpora generally tend to have different structure, use different tagsets and so on we plan only to allow to filter a searching corpus according to metainformation. If (like in the above example) two corpora use very similar annotations they may be compilled as a single corpus with some additional metatags. Hence, it is mainly a task for a person who adapts a corpus for Poliqarp. In the Poliqarp GUI it may be worth considering a way to predefine some default part of a query (like those filters).
