Indices Filter
editIndices Filter
editThe indices
filter can be used when executed across multiple indices,
allowing to have a filter that executes only when executed on an index
that matches a specific list of indices, and another filter that executes
when it is executed on an index that does not match the listed indices.
{ "indices" : { "indices" : ["index1", "index2"], "filter" : { "term" : { "tag" : "wow" } }, "no_match_filter" : { "term" : { "tag" : "kow" } } } }
You can use the index
field to provide a single index.
no_match_filter
can also have "string" value of none
(to match no
documents), and all
(to match all). Defaults to all
.
filter
is mandatory, as well as indices
(or index
).
The fields order is important: if the indices
are provided before filter
or no_match_filter
, the related filters get parsed only against the indices
that they are going to be executed on. This is useful to avoid parsing filters
when it is not necessary and prevent potential mapping errors.
