6. Search content relevance testing based on keyword search and result shown

On this pattern you can easily start writing test cases such as:
1. Test home page content and cursor is at the text box to let you start typing.
2. If a keyword is searched make sure result displayed on the top links, should have those keyword on their webpages, verify by visiting the links to make sure it works
3. Search a keyword with 'I am feeling lucky' and make sure the content is most relevant.
4. Test max and min length of search text box
5. When you search, just type few words with incorrect spelling or incomplete word, verify that it gives you a suggestion. Validate suggestion link redirects you with result of correct keyword search.

And so on...

Order in which result are displayed should be tested.... i.e. page ranking logic

3.After entering string it dispalys correct result
4.check maximum length or minimum length of search string
