GEOSEARCH key [FROMMEMBER member] [FROMLONLAT longitude latitude] [BYRADIUS radius m|km|ft|mi] [BYBOX width height m|km|ft|mi] [ASC|DESC] [COUNT count [ANY]] [WITHCOORD] [WITHDIST] [WITHHASH]

Return the members of a sorted set populated with geospatial information using GEOADD, which are within the borders of the area specified by a given shape. This command extends the GEORADIUS command, so in addition to searching within circular areas, it supports searching within rectangular areas.

This command comes in place of the now deprecated GEORADIUS and GEORADIUSBYMEMBER.

The query's center point is provided by one of these mandatory options:

• FROMMEMBER: Use the position of the given existing <member> in the sorted set.
• FROMLONLAT: Use the given <longitude> and <latitude>.

The query's shape is provided by one of these mandatory options:

• BYRADIUS: Similar to GEORADIUS, search inside circular area according to given <radius>.
• BYBOX: Search inside an axis-aligned rectangle, determined by <height> and <width>.

The command optionally returns additional information using the following options:

• WITHDIST: Also return the distance of the returned items from the specified center. The distance is returned in the same unit as specified for the radius or height and width arguments.
• WITHCOORD: Also return the longitude and latitude of the matching items.
• WITHHASH: Also return the raw geohash-encoded sorted set score of the item, in the form of a 52 bit unsigned integer. This is only useful for low level hacks or debugging and is otherwise of little interest for the general user.

By default, the command returns unsorted items. Two different sorting methods can be invoked using one of the following two options:

• ASC: Sort returned items from the nearest to the farthest, relative to the center.
• DESC: Sort returned items from the farthest to the nearest, relative to the center.

By default all the matching items are returned. It is possible to limit the results to the first N matching items by using the COUNT <count> option. When ANY is provided the command will return as soon as enough matches are found, so the results may not be the ones closest to the specified point, but on the other hand, the effort invested by the server is significantly lower. When ANY is not provided, the command will perform an effort that is proportional to the number of items matching the specified area and sort them, so to query very large areas with a very small COUNT option may be slow even if just a few results are returned.

*Return value

Array reply, specifically:

• Without any WITH option specified, the command just returns a linear array like ["New York","Milan","Paris"].
• If WITHCOORD, WITHDIST or WITHHASH options are specified, the command returns an array of arrays, where each sub-array represents a single item.

When additional information is returned as an array of arrays for each item, the first item in the sub-array is always the name of the returned item. The other information is returned in the following order as successive elements of the sub-array.

1. The distance from the center as a floating point number, in the same unit specified in the shape.
2. The geohash integer.
3. The coordinates as a two items x,y array (longitude,latitude).
