# Index Documents

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

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