Common Metadata Repository: How do I perform a search?

There are several ways to search the CMR system using the RESTful principles, which include employing:

• The API calls and parameters with the GET method

• The API calls and parameters with the POST method

• A JSON query language with a POST method

• The Alternative Query Language (AQL)

The most popular and preferred method is to use the API calls and parameters with the GET or POST methods. For more detailed information, see the API documentation located at /collaborate/open-data-services-and-software/api/cmr-api.

Note: The CMR URL character limit is currently set to take roughly 500k characters. Clients using the GET Search API with query parameters should be careful not to exceed this limit or an HTTP response of 413 FULL HEAD will be returned. Clients who expect that the query URL could exceed 500k characters should use the POST method as opposed to the GET method for searching.
