+
+added[1.0.0.Beta2]
+
+The `execution` option controls how the range filter internally executes. The `execution` option accepts the following values:
+
+[horizontal]
+`index`::       Uses field's inverted in order to determine of documents fall with in the range filter's from and to range
+`fielddata`::   Uses field data in order to determine of documents fall with in the range filter's from and to range.
+
+In general for small ranges the `index` execution is faster and for longer ranges the `fielddata` execution is faster.
+
+The `fielddata` execution as the same suggests uses field data and therefor requires more memory, so make you have
+sufficient memory on your nodes in order to use this execution mode. It usually makes sense to use it on fields  you're
+already faceting or sorting by.

-The result of the filter is automatically cached by default. The
+The result of the filter is only automatically cached by default if the `execution` is set to `index`. The
 `_cache` can be set to `false` to turn it off.
