open source - Evaluating search engines : free alternatives for TREC -


i evaluating several open-source search engines each other. wanted using trec data collections such wt10g or enterprise data collection...

ms research has released test corpora non-commercial use, intended learning rank experiments potentially useful more general ir development.
