    Here's the structure of the commit operation:
    <commit waitSearcher="" softCommit="" expungeDeletes="" />

    Optional attributes for the "commit" element:
    • waitSearcher: (default: true) — if true, wait until a new searcher is opened and registered as the main query searcher, making the changes visible.

    • softCommit: (default: false) — if true, perform a soft commit.

    • expungeDeletes: (default: false) — if true, expunge deletes in the segments that the commit merged.
  2. Example of an XML message to commit changes
    Example:
    <commit waitSearcher="false" softCommit="true" expungeDeletes="true" />

  3. Example of commit operation using the update request handler
    Here's an example of an http request:
    $ curl http://localhost:8983/solr/COLLECTION-NAME/update \
-H "Content-Type: text/xml" \
--data-binary '<commit waitSearcher="false" softCommit="true" expungeDeletes="true" />'
  4. Example of commit operation using the update request handler (without the XML message)
    Here are examples of http requests (without the XML message):
    http://localhost:8983/solr/COLLECTION-NAME/update?commit=true

    http://localhost:8983/solr/COLLECTION-NAME/update?commit=true&waitSearcher=false&softCommit=true&expungeDeletes=true

    http://localhost:8983/solr/COLLECTION-NAME/update?stream.body=<commit/>
