=== Versioning

Each document indexed is versioned. When deleting a document, the
`version` can be specified to make sure the relevant document we are
trying to delete is actually being deleted and it has not changed in the
meantime. Every write operation executed on a document, deletes included,
causes its version to be incremented.
Each document indexed is versioned. When deleting a document, the `version` can
be specified to make sure the relevant document we are trying to delete is
actually being deleted and it has not changed in the meantime. Every write
operation executed on a document, deletes included, causes its version to be
incremented. The version number of a deleted document remains available for a
short time after deletion to allow for control of concurrent operations. The
length of time for which a deleted document's version remains available is
determined by the `index.gc_deletes` index setting and defaults to 60 seconds.
