Let’s say that I have A, B, C, D, E, F, G as metadata and only A and C have “classification” as datatype, the rest of them are “free text”. Is it possible to formulate a query like: “look for the word apple in all texts having as metadata G”? Any help would be highly appreciated.

The best way of doing this is to compile a subcorpus for this restriction, using the "Scan text metadata" option.  This ensures that CQPweb is aware of your search constraints and can e.g. carry out a collocation analysis within the subcorpus (rather than relative to the full corpus).

A quicker way is to use CQP query syntax and include a global constraint for the metadata, e.g.

	<your CQP query> :: match.text_G = "…";

Best,
Stefan
