boost	double	The factor by which the score of the suggestion should be boosted. The score is computed by multiplying the boost with the suggestion weight.
context	SearchContext	The value of the category to filter/boost on.
neighbours	GeoHashPrecision[]	An array of precision values at which neighboring geohashes should be taken into account. Precision value can be a distance value ( 5m, 10km, etc.) or a raw geohash precision ( 1.. 12). Defaults to generating neighbors for index time precision level.
precision	GeoHashPrecision	The precision of the geohash to encode the query geo point. Can be specified as a distance value ( 5m, 10km, etc.), or as a raw geohash precision ( 1.. 12). Defaults to index time precision level.
prefix	boolean	Whether the category value should be treated as a prefix or not.
