This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.



CloudSearch is a flexible plugin that allows you to leverage the search index power of Amazon CloudSearch in your WordPress site.
To use this plugin you’ll need an Amazon Web Services account. Attention: Amazon CloudSearch is a paid service and will require a credit card.

Before you can start using CloudSearch, the plugin needs to be activated and configured. Activate the plugin, then go to the menu “CloudSearch -> Settings” (you can find this menu in the sidebar of your WordPress admin panel).
Fill the form data:

  • Enter Amazon access key ID, Amazon secret access key and Amazon region for your account (look for “Security Credentials” in your Amazon console to retrieve these data)
  • Enter your CloudSearch index search endpoint and the domain name (I suggest to create the CloudSearch index before you start the plugin configuration)
  • Schema settings
  • Other settings

* At least WordPress 4.4 version mandatory (for WP_Term support)
* Changed APIs output from an array of IDs to an array of object composed by the entity ID and the entity type

Minimum requirements:

  • WordPress Version 4.4
  • PHP Version 5.3
  • Amazon Web Services account with CloudSearch enabled


  1. Go to CloudSearch -> Settings
  2. Enter your Amazon access key ID, Secret access key and the Amazon region where you have created the CloudSearch index
  3. Enter a Search endpoint and the Domain name. Get these info in your CloudSearch dashboard in AWS Console
  4. Choose post types, custom fields and custom taxonomies that you want to export to the CloudSearch index
  5. Set up other settings or leave defaults
  6. Save settings.
  7. Go to CloudSearch -> Manage
  8. Click the action Create index, Run indexing and Sync all documents. Between every action wait until the Status field is Active, then go on with the next task
  9. After these operation your index is ready, now you can search documents in your CloudSearch index

How much does the plugin cost?

There is no charge for the plugin. The only charges you incur are for usage of Amazon CloudSearch.

Works on multisite?

Yes, for every site you have a specific configuration but you cannot search documents between different sites with defaults configuration. You need to customize search scripts.

Does the plugin support multi languages?

The plugin does not work with other languages plugins. However, there is a alternative and simple way to work with other languages. An explanation could be found in the plugin help page.

Which post types and fields are indexed by default? How do I modify indexed schema?

By default, only posts and standard fields are indexed. To modify this, in the admin “Setting” section you can add other post types, fields and taxonomies (also custom objects).

Supports facets?

Yes, you can use API for retrieve facet information.

Supports field weightings?

Yes, you can add a weight to some fields to boost up the relevance of the results.

Supports for WooCommerce product tags and EDD tags?

Yes, you can manage WooCommerce product tags and EDD tags simply adding a little code in a custom plugin or in the functions.php of your theme.

This plugin works really well and makes integrating Amazon CloudSearch with your Wordpress site totally seamless. The documentation is comprehensive and helpful. The support threads have lots of useful information, as well. Andrea (the developer of this plugin) is very responsive to questions and even helped me fix an issue with my search results page with Divi. All around A+++ and highly recommend!

If you use Wordpress and are hosted on Amazon and need the best search functionality there is, look no further than this plugin. It rocks. I have tried it all, the internal Wordpress search (which is a joke for a serious blog), Relevanssi (great but still uses a lot of resources) and ended up with this plugin. It is easy to configure and uses the power of Amazon to present quick search results to the visitor. Keep on rockin’ Andrea. And thanks for implementing our ideas/requests for search suggestions and your quick replies on our questions.
