| | public void | testSearch()This test performs a number of searches. It also compares output
of searches using multi-file index segments with single-file
index segments.
TODO: someone should check that the results of the searches are
still correct by adding assert statements. Right now, the test
passes if the results are the same between multi-file and
single-file formats, even if the results are wrong.
