I counted the collections listed in Summary of All Results, and they definitely don equal the number of collections the results page says was searched. Why is there a discrepancy?

A. The collection count on the results page (i.e. “*some-number* of 262 sources complete” at the top) does indicate the correct number of collections being searched. This number is larger than the number in the Summary of All Results because Explorit is a federated search that is searching other federated collections. For instance, www.science.gov is included in the collections being searched. www.science.gov, itself, searches around 50 other collections. The Summary of All Results identifies all the collections Explorit searches, which means if Science.gov is down, approximately 50 collections will be missing from the results pages.
