+module: ec2_ami_find
+version_added: 2.0
+short_description: Searches for AMIs to obtain the AMI ID and other information
+description:
+  - Returns list of matching AMIs with AMI ID, along with other useful information
+  - Can search AMIs with different owners
+  - Can search by matching tag(s), by AMI name and/or other criteria
+  - Results can be sorted and sliced
+author: Tom Bamford
+notes:
+  - This module is not backwards compatible with the previous version of the ec2_search_ami module which worked only for Ubuntu AMIs listed on cloud-images.ubuntu.com.
+  - See the example below for a suggestion of how to search by distro/release.
+options:

+    description:
+      - The AWS region to use.

+    aliases: [ 'aws_region', 'ec2_region' ]
+  owner:
+    description:
+      - Search AMIs owned by the specified owner
+      - Can specify an AWS account ID, or one of the special IDs 'self', 'amazon' or 'aws-marketplace'
+      - If not specified, all EC2 AMIs in the specified region will be searched.
+      - You can include wildcards in many of the search options. An asterisk (*) matches zero or more characters, and a question mark (?) matches exactly one character. You can escape special characters using a backslash (\) before the character. For example, a value of \*amazon\?\\ searches for the literal string *amazon?\.
