I want to implement auto suggest functionality in Google App Engine (GAE/GWT).
The client side of the implementation works fine with GWT SuggestBox and RPC. My main issue is the server side of the implementation. I tried the Google search API but it seems that there is a limitation of 250MB of total indexed data and the search can be performed on complete words and not parts of each word!
How should I approach this? I read that lucene or solr is not supported in GAE. I would appreciate your thoughts on this.
You can achieve a basic text search using these techniques described here: http://googlecode.blogspot.com.br/2010/05/google-app-engine-basic-text-search.html
In short:
Build a query using content >= yourQuery && content < yourQuery + "\ufffd"
, where the content
property of your entity can be a String or a List of Strings.
