/**
 * Test for bug 395739 to make sure the feedback to the search results in those
 * entries getting better ranks. Additionally, exact matches should be ranked
 * higher. Because the interactions among adaptive rank and visit counts is not
 * well defined, this test holds one of the two values constant when modifying
 * the other.
 *
 * This also tests bug 395735 for the instrumentation feedback mechanism.
 *
 * Bug 411293 is tested to make sure the drop down strongly prefers previously
 * typed pages that have been selected and are moved to the top with adaptive
 * learning.
