If your user account has the Read , Write, or Own permission level on a data file in DME, you can search you can search for that data. You can generate a list of such data files that match a search query. You can also specify a search path to narrow the search. The list provides the full path to each file in DME.
...
To search for data:
- In your file local system, create a JSON file that specifies a search query. For more information, refer to Building a Query to Search for Data via the CLU.
Run the following command:

The following table describes each parameter:
Parameter Description [-D <REST-response>]
An optional parameter, specifying a path and filename in your file local system. The system always creates a response file:
- If you specify this parameter, the system saves the response from the server to the specified file in the specified location.
- If you omit this parameter, the system saves the file as query-dataobject-response-header.tmp in your home directory.
[-o <output-file>]
An optional parameter, specifying a path and filename in your file local system. The system always creates a query output file:
- If you specify this parameter, the system saves the query output to the specified file in the specified location.
- If you omit this parameter, the system prints the query output to standard output and saves the file as query-dataobject-response-message.json.tmp in your home directory.
<criteria.json>
A path and filename for a JSON file in your file local system, containing the compound query for the search. [search-path]
An optional parameter, specifying the path to the collection in DME in which you want to search.
For example, consider the following criteria.json file. When you perform a query, the system requires it in the context of a compoundQuery element with a join operator, even if it contains only one simple query.

With the above criteria.json file, the following command generates a list of data files in DME, in Project_1 and subcollections, that are size 10 or smaller. The output provides a total count of results and lists only the first page (the first 100 paths).
