Role of the SharePoint Search Result Web Part

The Search & Preview SharePoint Search Result Web Part submits an incoming query to the search database receives the search results and displays them on the page, usually in a table. The query is usually established when the user fills out a search form on the referring page, though it is also possible that the referring page is the same as the result page (e.g., when the result page also has a search-again form). You can also configure the Web part to generate the same query every time, thereby enabling it to show a specific type of results without receiving any query.

The Search & Preview SharePoint Search Result Web Part interacts with the content index and other features supplied by the Microsoft Office SharePoint Server (SharePoint) package.
