# Content Indexing Pipeline

Users can choose one of the following two methods to index documents in content insight from their applications.

1\.     Use the REST API for uploading document and additional metadata. The metadata is also indexed and can be used to augment the content search. Alternatively, the metadata can be searched without including the content

2\.     Publish the message which includes the document metadata and path to a Message Queue. The engine can then retrieve the document from the content store and index it along with the other metadata in the message. The results are published back to another queue.

Once the data is available in the index store, the REST based search APIs can be used to retrieve the document id and other related information.
