DELETE /website/blog/123Deleting a Document
The syntax for deleting a document follows the same pattern that we have seen
already, but uses the DELETE method :
If the document is found, Elasticsearch will return an HTTP response code
of 200 OK and a response body like the following. Note that the _version
number has been incremented:
{
"found" : true,
"_index" : "website",
"_type" : "blog",
"_id" : "123",
"_version" : 3
}If the document isn’t found, we get a 404 Not Found response code and
a body like this:
{
"found" : false,
"_index" : "website",
"_type" : "blog",
"_id" : "123",
"_version" : 4
}Even though the document doesn’t exist (found is false), the
_version number has still been incremented. This is part of the internal
bookkeeping, which ensures that changes are applied in the correct order
across multiple nodes.

As already mentioned in [update-doc], deleting a document doesn’t immediately remove the document from disk; it just marks it as deleted. Elasticsearch will clean up deleted documents in the background as you continue to index more data. |
