In an attempt to make Web navigation easier for surfers, Internet search giant Google is rolling out a more streamlined design of its main site, with a notably brighter corporate logo; as well as adding a few search enhancement tools.

The pure design changes, other than the freshly-polished version of the Mountain View, California-based company’s logo, also include colorful icons on the left-hand side that facilitate filtering of content by categories like blogs, images, and books.

Furthermore, Google has added a more unified appeal to the layout and feel of the search pages; and a new column of search options that reveals the kind of search a user has typed.

Noting that the changes made to the Google search engine essentially aim at keeping pace with the “continually evolving and adapting” Web and its users, Nundu Janakiram, Google’s product manager for search, elaborated that the redesign of the Google search page also includes technological changes, like the introduction of algorithms for selecting the most apt refinement tools to serve up based on the search query.

As such, searches of blogs can be narrowed by time down to the most recent 10 minutes; news searches can be narrowed by time to the last one hour; and books searches to within a century. Moreover, searches for images can also be refined by size, type, and color.
