If you are going to build a search engine, you'll need all of the
Tweets to search over them. For this, you'll want to take the Firehose
of all public statuses.

You'll need a commercial data license to do this. Email api to get started.

I plan to build a search engine which would utilize the search APIs.
Should I be using the Twitter Search API or the Streaming API to do
the same?
What is the difference between the two and would the Streaming API
work on the Google App Engine?
