 Description   
TRECResultMatching bypasses normal matching by "retrieving" directly from a TREC run (as opposed to the entire collection). However, unless an expected result set size is explicitly provided (through trecresults.matching.number.docs), it creates a ResultSet object to hold every document in the collection, which penalises efficiency.

trecresults.matching.number.docs should have a default value, probably 1000 (the typical TREC run size). If more than this default number of objects is loaded, an exception should be raised.

Tagging for 3.1, as TRECResultMatching are moving into CORE for 3.1

The version committed for TREC-214 resolves this issue. In particular, the default size is set to 1000. However, no warning is raised if there are more than this amount of results available.
