# Delete Documents and Ranges of Documents

If you identify individual documents or ranges of documents by their ID, you can delete them from the Content component data index by sending a DREDELETEDOC action (case sensitive) from your Web browser:

    http://ContentHost:indexPort/DREDELETEDOC?Docs=docIDs

where:

`ContentHost` | is the IP address or host name of the machine on which the Content component is installed.
`indexPort` | is the Content component index port (specified as IndexPort in the `[Server]` section of the Content component configuration file).
`docIDs` | is one or more individual document IDs or ranges of document IDs that specify the documents that you want to delete. Use one or a combination of the following two formats: `docID`. Specify the IDs of one or more documents. To specify multiple document IDs, separate them with plus symbols (there must be no space before or after a plus symbol). `range=[min_docID,max_docID]`. Enter the document ID of the first and last document in a range of documents that you want to delete. If you want to combine the formats, separate them with plus symbols (there must be no space before or after a plus symbol).

For example:

    http://MyHost:20001/DREDELETEDOC?Docs=3+5+range=[7,10]

This action uses port `20001` to delete the documents with the DocIDs `3`, `5`, `7`, `8`, `9`, and `10` from the Content component, which is located on a machine with the host name `MyHost`.
