The percolator and filters in aliases by default enforce strict query parsing.

This section discusses the changes that you need to be aware of when migrating
your application from one version of Elasticsearch to another.
As a general rule:
* Migration between major versions -- e.g. `1.x` to `2.x` --
requires a <<restart-upgrade,full cluster restart>>.
* Migration between minor versions -- e.g. `1.x` to `1.y` -- can be
performed by <<rolling-upgrades,upgrading one node at a time>>.
See <<setup-upgrade>> for more info.
