I believe we need something like AskSteem to be integrated instead of Google or any other search engine.

The problem is, when you search Google or any search engine, the returned pages are those indexed - not the ones created on the blockchain. Of course, steemit.com holds a lot of authority and almost all of the pages are indexed (Haven't done any calculations for percentage or indexing time), but there's still the risk of not finding the results you NEED.

Using AskSteem or some other form of blockchain search engine guarantees that you'll find all posts regardless their age or creation time. They are all 'indexed' naturally since they are stored on the blockchain.
