Contextual search is a form of optimizing web-based search results based on context provided by the user and the computer being used to enter the query. [1] Contextual search services differ from current search engines based on traditional information retrieval that return lists of documents based on their relevance to the query.

Any text transcluded from a template is indexed as if it were really present on its target page. (In other words, by default, a keyword search is done on the text of the rendered Wikipedia page, not on the page source itself. However, you can change this by using insource:keyword to search the source markup instead of the rendered page.)
