+# Indices Filter
+
+> More info about indices filter is in the [official elasticsearch docs][1]
+
+The 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.
+
+## Simple example
+
+```JSON
+{
+ "indices" : {
+ "indices" : ["index1", "index2"],
+ "filter" : {
+ "term" : { "tag" : "wow" }
+ },
+ "no_match_filter" : {
+ "term" : { "tag" : "kow" }
+ }
+ }
+}
+```
+
+And now the query via DSL:
+
+```php
+$termFilter1 = new TermFilter('tag', 'wow');
+$termFilter2 = new TermFilter('tag', 'kow');
+
+$indicesFilter = new IndicesFilter(
+ ['index1', 'index2'],
+ $termFilter1,
+ $termFilter2
+);
+
+$search = new Search();
+$search->addFilter($indicesFilter);
+
+$queryArray = $search->toArray();
+```
