So you want to search the content on your enterprise’ SharePoint portal but your corporate intranet search isn’t integrated with your SharePoint implementation yet. Most organizations start with SharePoint as a collaboration tool that lives along with their other corporate intranet / internet platforms and isn’t fully integrated with their search platform.
I am going to show you a simple way to search your SharePoint content no matter what site you are on assuming you are using IE as your browser. Trick lies with the IE search providers. As you probably know you can Manage Search providers on the IE browser. In the screen below, I have Google setup as my default search provider.

To create a custom IE Search provider:
- Go to : http://www.microsoft.com/windows/ie/searchguide/en-en/default.mspx

-
In the "Create your own" section:
Note: To find out the correct URL for step 3, navigate to your SharePoint site and search for the term “TEST”. Copy and paste the url from your search results page.
- Install. You should see the new search provider “EMC SharePoint” show in your search providers.

Enter a search term and try it out. Now you have the ability to search your SharePoint content directly from your browser.
