[CWB] Re: Querying more than one corpus at a time

Nope, there's no way of doing this within CQP.  Query results are stored as a flat table of corpus positions, i.e. offsets into a single encoded corpus.   This representation is very compact and efficient, but you cannot combine query results from different corpora.  (Some other functions -- such as "group" and "sort" -- rely on query results to come from a single corpus, too, so they can operate on lexicon IDs instead of full strings for greater efficiency.)
