Amazon CloudSearch vs. Bonsai vs. Elasticsearch

Amazon CloudSearch enables you to search large collections of data such as web pages, document files, forum posts, or product information. With a few clicks in the AWS Management Console, you can create a search domain, upload the data you want to make searchable to Amazon CloudSearch, and the search service automatically provisions the required technology resources and deploys a highly tuned search index.

Your customers expect fast, near-magical results from your site search. Help them find what they’re looking for with Bonsai. We set up and manage the servers for you, so integration is quick and easy, and you can stay focused on building an awesome site.

Elasticsearch is a distributed RESTful search engine with over 50 million downloads. Elasticsearch, Logstash, Kibana and Beats make up the "Elastic Stack" developed by Elastic. Hosted Elasticsearch (Elastic Cloud) is also provided.
