[CWB] Querying more than one corpus at a time

[Alberto Simões]

Hello,

Is there any way to query more than one corpus (I want to do it for 
monolingual and parallel) at a time?

Or the trick is to select one, query and save result, select the second, 
query and save result, and then cat the results together?

If so, is there any way on keeping information on which corpus does the 
sentence is from?

What would be the more efficient way?

Thank you
