Now that we understand some of the background about searches and how the indexing works, it is time to index some of our own data. In the case of developing applications on top of Google App Engine, our source of data to be indexed would most likely be datastore. In this section, we will first generate some sample data with interesting characteristics and next we will see how we can index that data using the App Engine's search API.
