How to Create an Enterprise Search Center in SharePoint 2010

Suppose we have some requirements that we want to see items that are not documents in our search results. In such situations we need to set up a Custom Search Center where they can search for either/all content, people, or just documents. Here we are going to create a new Search Center and a new tab for only documents. When users select this tab, only items that are documents appear in their search results.

Some of the new features of SharePoint 2010 Search are listed below

Boolean query syntax has finally been introduced. These include AND, OR and NOT operators in your search queries.
Suggestions whilst typing and after running search queries, a feature that we have come to love with major search engines such as Google and Bing.
Integrating SharePoint Enterprise Search with Windows 7, allowing end users to utilize the Windows 7 search box to locate SharePoint 2010 content.
Results display has been refined to provide filters for search results such as document type, categories and managed properties.
View in Browsercapabilities, allows end users to view documents within their own browser utilizing Office Web Apps and not having to rely on launching the necessary Microsoft Office Application, or even the need for having it installed on their local machine. This is handy when browsing your SharePoint site via Kiosks and Internet Cafes that may not be running the Microsoft Office Suite.
There have been a number of improvements to People Search, including phonetic name and nickname matching, and improved relevance and self-search.
