Many librarians like to default to an advanced search page that shows a variety of limits, field searches, boxes for constructing Boolean search statements, and unique features of the search system. Google's many databases and frequent user interface changes show a variety of approaches to advanced searching. Google often leads the way in search design. Since others copy later, Google's current advanced search experiments may be a harbinger of search design to come at many other sites. With Google's latest homepage redesign, which replaces the black bar at the top of the page with a new Google bar that drops down from the logo, the gear options icon is gone, and no link to advanced search exists on the homepage. One impetus for change has been the addition of post-search limit options. Rather than choosing appropriate limits pre-search from an advanced search page, searchers can choose limits post-search using search tools on the left-hand side of the page.
