As it mentioned in Elasticsearch documents, these kinds of request can support IgnoreUnmapped which is useful for searching on multiple indices. But as I tried to set that to true I found out it doesn't exist.
GeoBoundingBoxQuery
GeoDistanceQuery
GeoPolygonQuery

Thanks for submitting this @alrz1999. Very much appreciated! Would you be able to retarget this to 7.x? The master branch is going to see some major changes in 8.0 as we move to code generating a lot of these types. It should be largely fixed by that work when we're ready to merge it. These should make their way into a 7.x release ideally. If you don't have time I can pick it up at some point.

Thanks for reviewing. I opened another pull request to add it on 7.x.

Closing this as merged into 7.x in another PR.
