# Index Overview

You can index only files in XML or IDX format into HPE IDOL Server. If the data that you want to index into HPE IDOL Server is in XML format, you can index it directly into HPE IDOL Server, without having to first import it (convert its content and metadata to IDX).

HPE IDOL connectors use the `DREADD` and `DREADDDATA` index actions to index data into HPE IDOL Server. You also can use these actions to directly index data into HPE IDOL Server.

Note: Before you index data into HPE IDOL Server, review the setup instructions described in Configure Content Storage.

If your data is not in XML format, you must first import it. You can import data using one of three methods.

- Import with a connector. The HPE IDOL connectors (for example, File System Connector, HTTP Connector, Oracle Connector, and so on) retrieve documents from different repositories and import them into IDX or XML file format. Refer to the appropriate connector guide for further information on how to import documents.

- Import manually. You can create a text file in either XML or IDX format, which contains the information that you want to index into your HPE IDOL Server in specific HPE IDOL Server fields.

- Import with IDOL Admin. You can use the wizard on the Index tab on the Console page in the Control section of IDOL Admin to submit data for IDOL Server to index. For more information, refer to the IDOL Admin User Guide.

- Index with a connector. The HPE IDOL connectors index the IDX files that they create into the HPE IDOL Server to which they connect. Refer to the appropriate connector guide for detailed information on how to index documents.

- Index directly. You can index XML and IDX files into an HPE IDOL Server by issuing an HTTP request from your Web browser.

Depending on where the data to index is located, the indexing steps for each document take place in the following order.

Local document (accessed through the file system) | Remote document (accessed over the indexing port)
--- | ---
HPE IDOL Server receives a file path. HPE IDOL Server opens the file and reads the document data. HPE IDOL Server indexes the document. | HPE IDOL Server receives a stream of data over the port. HPE IDOL Server saves the data locally. HPE IDOL Server opens the local file and reads the document data. HPE IDOL Server indexes the document.
