/**
 * Test for bug 406358 to make sure frecency works for empty input/search, but
 * this also tests for non-empty inputs as well. Because the interactions among
 * DIFFERENT* visit counts and visit dates is not well defined, this test
 * holds one of the two values constant when modifying the other.
 *
 * Also test bug 419068 to make sure tagged pages don't necessarily have to be
 * first in the results.
 *
 * Also test bug 426166 to make sure that the results of autocomplete searches
 * are stable.  Note that failures of this test will be intermittent by nature
 * since we are testing to make sure that the unstable sort algorithm used
 * by SQLite is not changing the order of the results on us.
