[CWB] CQP s-attributes constrains: select text_ids for searching

[Stephanie Evert]

Dear Ramiro,

I suppose that you're talking about doing the subcorpus search directly in CQP?  Then you can simply restrict your matches to those in the desired documents.  You can either do it in the CQP query

	.... query ... within text :: match.text_id = "...";

or you can make a subcorpus of all relevant texts

	Sub = <text_id = "..."> [] expand to text;

then activate it for a subcorpus search:

	Sub;
	... query ...;

The inconvenience is that you can use word lists with s-attributes, so this can be tedious (or not work at all) if you have a very long list of text IDs. You have to match against a regular expressions that is essentially a disjunction of the relevant text IDs.

Hope this helps,
Stephanie
