# Adds Parameter

The `adds` parameter specifies XML that describes the document to ingest. A document must have a unique reference. It can consist of metadata only, content only, or metadata and content. You can specify content using either plain text or a file.

The following XML describes a document with metadata and a file:

    <adds>
       <add>
          <document>
             <reference>http://www.example.com/</reference>
             <metadata name="Field1" value="Value1"/>
             <metadata name="Field2" value="Value2"/>
          </document>
          <source filename="MyFile.doc" lifetime="permanent"/>
       </add>
    </adds>

You can specify XML metadata using the `xmlmetadata` element:

    <adds>
       <add>
          <document>
             <reference>http://www.example.com/</reference>
             <xmlmetadata>
                <Field1>Value1</Field1>
                <Field2>
                   <SubFieldOne>First</SubFieldOne>
                   <SubFieldTwo>Second</SubFieldTwo>
                </Field2>
             </xmlmetadata>
          </document>
          <source filename="MyFile.doc" lifetime="permanent"/>
       </add>
    </adds>

In the preceding examples the source is specified as a file on the file system. You can also specify the source using a base64 encoded string:

    <adds>
       <add>
          <document>
             <reference>http://www.example.com/</reference>
          </document>
          <source content="U29tZSB0ZXh0DQo="/>
       </add>
    </adds>

You can also specify the plain text for each section using the pages element:

    <adds>
       <add>
          <document>
             <reference>http://www.example.com/</reference>
             <pages content="Page 1 content"/>
             <pages content="Page 2 content"/>
          </document>
       </add>
    </adds>

Multiple documents can be ingested by specifying multiple `<add>` elements. The following table describes the various XML elements.

XML element | Description
--- | ---
`add` (required) | The `add` element describes a single document that should be ingested by CFS. To ingest multiple documents, use further `add` sections. Each `add` section should contain a `document` element that describes the document to be indexed. It can also contain a `source` which describes a binary file to be ingested.
`document` (required) | The `document` element describes the document content and metadata. Each `document` element must contain a `reference` element giving the unique reference for this document. It can also contain `metadata`, `xmlmetadata` or `pages` elements.
`reference` (required) | The `reference` element is used to provide a unique reference (DREREFERENCE) for the document.
`metadata` (optional) | The `metadata` element is used to provide a key value pair describing metadata to be ingested. `name` is the name of the metadata field `value` is the value of the field
`xmlmetadata` (optional) | The `xmlmetadata` element contains any XML metadata that should be associated with the document.
`pages` (optional) | The `pages` element is used to specify any filtered document content that should be sent with the document. You can use multiple `pages` elements, and each of these will map to a separate DRESECTION.
`page` (optional) | The `page` element is used to specify the content for a single DRESECTION. Specify the content as plain text.
`source` (optional) | The `source` element describes the location or content of the binary file. You must set either the `filename` or `content` attributes. `Filename` is the full path to the document. `Content` is the binary content of the document as a base64 string. If you specify the location of a file using `filename` you must also set the `Lifetime` attribute. This attribute can take one of two values: `Permanent` instructs CFS not to delete the file. `Temporary` means that CFS should delete the file after it has been ingested. NOTE: The `Lifetime` attribute is ignored when you ingest an IDX file. CFS does not delete IDX files that are ingested.

## Ingest an IDX File

You can ingest an IDX file by using the <`source>` element to specify the path to the file.

    <adds>
       <add>
          <source filename="data.idx" />
       </add>
    </adds>

If the `<add>` element includes a `<document>` element specifying a reference, metadata, or content:

- The reference is ignored. The references in the IDX file are always used.
- The metadata is merged with the metadata for every document in the IDX file.
- The content is inserted before the content of every document in the IDX file.

If the IDX file contains sectioned documents, the sections are merged into a single document.

If CFS fails to parse the IDX file, and no documents were successfully extracted, the IDX is processed as a regular file. If CFS fails to parse the IDX file, but at least one document was successfully extracted, an error is logged and the remainder of the file is not processed.
