 -----
-Allows basic access to a [Cloudant](http://cloudant.com) database. Currently
-it only have one node that supports `insert`, `update` and `delete`
-operations.
+Allows basic access to a [Cloudant](http://cloudant.com) database to
+`insert`, `update`, `delete` and `search` for documents.
 
 To **insert** a new document into the database you have the option to store
 the entire `msg` object or just the `msg.payload`. If the input value is not
 in JSON format, it will be transformed before being stored.
 
 For **update** and **delete**, you must pass the `_id` and the `_rev`as part
 of the input `msg` object.
+
+To **search** for a document you have two options: get a document directly by
+its `_id` or use an existing [search index](https://cloudant.com/for-developers/search/)
+from the database. For both cases, the query should be passed in the
+`msg.payload` input object as a string.
+
+When getting documents by id, the `payload` will be the desired `_id` value.
+For `search indexes`, the query should follow the format `indexName:value`.
