    Recreate a Milvus Collection

    Table of Contents

    Use this process to:

    • Recreate a lost Milvus collection.

    • Create a Milvus collection for a different field.

    • Create a Milvus collection that uses a different encryption model.


    • Used the Smart Answers pipeline to index data, which created the Milvus and Solr collections.

    • The created Solr collection still exists, which is used as the Source Collection.


    1. Create the Milvus collection. See Create Collections in Milvus for more information.

      If the Milvus collection still exists and you want to overwrite it, select the Override Collections checkbox. This option deletes the current collection, allowing you to create a new collection.
    2. Edit the Smart Answers Index Pipeline as follows:

      • Disable the Solr Indexer stage.

      • If you are creating a Milvus collection for a different field, or one that uses a different encryption model, access the Encode into Milvus stage and:

        • Specify the model, the Encoder Output Vector, and the Field to Encode.

        • Verify the Milvus Collection Name refers to the new Milvus collection.

    3. Navigate to the Datasources panel.

    4. Select Add a Solr connector and enter the following information:

      • Pipeline ID. Smart Answers pipeline

      • Solr Connection Type. SolrCloud

      • SolrCloud Zookeeper Host String. Execute the following curl command. The response displays the SolrCloud Zookeeper Host String value. In the following RESPONSE example, the value you would set for the SolrCloud Zookeeper Host String is ns-zookeeper-0.ns-zookeeper-headless:2181.

        curl -u USERNAME:PASSWORD https://FUSION_HOST:FUSION_PORT/api/searchCluster/default
