Hopefully it will assist anyone migrating from Solr to ES. The Using the geo_bounding_box query recipe shows how to filter on the square section, which is the most common case; Elasticsearch provides a way to filter user-defined polygonal shapes via the geo_polygon filter. The distance can be a numeric value, and then the distance_unit (either mi/miles or km can be set) controlling the unit. We will explore different ways to integrate them. Couchbase Server 2.

Field types that can participate in a distance query are date, date_nanos, and geo_point types. Some field operators are available as symbols (eg =, *, ^, gt) and others as words (eg geo_distance or -geo_distance - the dash is optional). In Elasticsearch, you can use the Lucene fuzzy operator '~' on each query word to apply a Levenshtein-distance with the number of typos you want to tolerate (for example 'george~1 clooney~1' means that you can tolerate one typo on 'george' and 1 typo on 'clooney').
