The familiar interface gives Google employees easy access to all kinds of data: contacts, shared bookmarks, refinements. Unfortunately, the design is kind of cluttered and the search takes a lot of time.
To add an alternate experimental front end and a checkbox to get to it is not very difficult. Click here to see the simple 3-step process.
This is an actual live screenshot showing what users see once they query for 'gfs'. You'll see that, in addition to the highly relevant search results, the user is able to see a variety of useful OneBox implementations such as Googler information and user-created bookmarks, they can segment their search to just tech documents, they can narrow their search even further, or, they can add their own KeyMatch if they didn't find the result they wanted.
MOMA is the name of Google's intranet. An ex-Googler tells its story:
"MOMA was designed by and for engineers and for the first couple of years, its home page was devoid of any aesthetic enhancements that didn't serve to provide information essential to the operation of Google. It was dense and messy and full of numbers that were hard to parse for the uninitiated, but high in nutritional value for the data hungry. MOMA displayed latency times, popular search terms, traffic stats for Google-owned properties and, at the center of it all, a large graph with colored lines labeled with the names of Muppet characters. (...)
I came to take it for granted that any information I needed about Google could be found on the intranet, from the status of products in development to the number of employees at any point in the company's history. (...)
Google eventually clamped down on who had access the complete state of the business; ostensibly because such information needed to be restricted unless everyone was going to be registered as an insider and restricted from freely buying and selling the company's stock."Google, Search, Search Engine, Google Intranet Search Engine, MOMA, Google Search Applicance
