Regardless of the outcome of #8142, we should at least enforce that when _source is enabled, it is sufficient to reindex. This change removes the excludes and includes settings, since these modify the source, causing us to lose the ability to reindex some fields. closes #10814

=== `_source`
|
|
|
|
The `_source` field is an automatically generated field that stores the
|
|
actual JSON that was used as the indexed document. It is not indexed
|
|
(searchable), just stored. When executing "fetch" requests, like
|
|
<<docs-get,get>> or
|
|
<<search-search,search>>, the `_source` field is
|
|
returned by default.
|
|
|
|
Though very handy to have around, the source field does incur storage
|
|
overhead within the index. For this reason, it can be disabled. For
|
|
example:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
{
|
|
"tweet" : {
|
|
"_source" : {"enabled" : false}
|
|
}
|
|
}
