# Searching for all DICOM series in HealthImaging
<a name="dicomweb-search-all-series"></a>

Use the `SearchDICOMAllSeries` API to search for all DICOM series across an HealthImaging [data store](getting-started-concepts.md#concept-data-store). Construct a request URL with supported DICOM data elements (attributes) to filter results. The API returns series search results in JSON format, ordered by `Series Number (0020,0011)` in ascending order (oldest to latest).

**To search for all DICOM series**  


1. Collect HealthImaging `region` and `datastoreId` values. For more information, see [Getting data store properties](get-data-store.md).

1. Construct a URL for the request, including all applicable Series elements. The URL is of the form:

   ```
   GET https://dicom-medical-imaging.{{region}}.amazonaws.com/datastore/{{datastoreId}}/series[?query]
   ```

   The following table lists the supported DICOM data elements (attributes).

[See the AWS documentation website for more details](http://docs.aws.amazon.com/healthimaging/latest/devguide/dicomweb-search-all-series.html)

1. Prepare and send your request. `SearchDICOMAllSeries` uses an HTTP GET request signed with [AWS Signature Version 4](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_sigv.html). The following example uses the `curl` command-line tool. Replace `{{region}}` with your AWS Region. Replace `{{datastoreId}}` with your data store ID.
