New field type GeoPointField, or "geopoint" in mapping JSON.
Currently structs and maps are considered when a mapping explicitly
marks a field as type "geopoint". Several variants of "lon", "lng", and "lat"
are looked for in map keys, struct field names, or method names.
New query type GeoBoundingBoxQuery searches for documents which have a
GeoPointField indexed with a value that is inside the specified bounding box.
New query type GeoDistanceQuery searches for documents which have a
GeoPointField indexed with a value that is less than or equal to the
specified distance from the specified location.
New sort by method "geo_distance". Hits can be sorted by their distance
from the specified location.
New geo utility package with all routines ported from Lucene.
New FilteringSearcher, which wraps an existing Searcher, but filters
all hits with a user-provided callback.
