The method of claim 1, wherein the arranging further comprises inserting a descriptor of each of the plurality of location entities derived from an address field of each of the plurality of location entities as a leaf node in a tree of the location descriptors. 10. The method of claim 9, wherein the arranging further comprises determining that at least two leaf nodes refer to a same instance if the at least two leaf nodes share a same descriptor and if the same descriptor is shared by a number of descendant nodes of a same parent, the number exceeding a first threshold number. 11. The method of claim 10, wherein the arranging further comprises combining the at least two leaf nodes, the combining including retaining one of the at least two leaf nodes at a lowest level in the hierarchy in which a number of occurrences of the at least two leaf nodes exceeds a second threshold number. 12. The method of claim 1, wherein the one location entity is determined to be the spatial outlier based on the number of other location entities within the predetermined distance of the one location entity not exceeding the threshold number. 13. The method of claim 1, wherein the one location entity is a yellow page entity and the other location entities are point of interest entities, and the determining further comprises: determining whether at least one of the point of interest entities is present within a predetermined distance of the yellow page entity; andin response to determining that no point of interest entity is present within the predetermined distance, determining that the yellow page entity is the spatial outlier. 14. An article of manufacture comprising: a storage device; anda plurality of executable instructions stored on the storage device which, when executed by a computing device, perform operations including: arranging a plurality of location entities into a hierarchy of location descriptors, the plurality of location entities including yellow page entities and point of interest entities, wherein individual ones of the location entities comprise global positioning system (GPS) coordinates captured by a GPS device;storing the plurality of location entities on a location search server, the location search server being remotely located from the computing device;determining whether one of the yellow page entities is a spatial outlier based at least in part on presence of at least one of the point of interest entities within a predetermined distance of the one of the yellow page entities, the at least one of the point of interest entities and the one of the yellow page entities sharing a location descriptor;in response to determining that the one of the yellow page entities is the spatial outlier, deleting the one of the yellow page entities; andsending an update to the location search server such that the plurality of location entities on the location search server reflects the deletion of the spatial outlier. 15. The article of claim 14, wherein the arranging further comprises inserting a descriptor of each of the plurality of location entities derived from an address field of each of the plurality of location entities as a leaf node in a tree of location descriptors. 16. The article of claim 14, wherein the determining further comprises, in response to determining that no point of interest entity is present within the predetermined distance, determining that the one of the yellow page entities is the spatial outlier. 17. The article of claim 14, wherein at least one of the yellow page entities comprises a location name, a location address, and a GPS position. 18. The article of claim 14, wherein the operations further comprise segmenting address fields of the location entities into location descriptors. 19. A system comprising: a processor of a computing device; andlogic configured to be executed by the processor to perform operations including: sending a plurality of location entities to a location search server for storage on the location search server, wherein individual ones of the location entities comprise global positioning system (GPS) coordinates captured by a GPS device, and wherein the location search server is remotely located from the computing device;segmenting address fields of a plurality of location entities into location descriptors, the segmenting including either or both of: segmenting based on commas and/or other characters indicating a separation between two or more terms; andsegmenting based at least in part on one or more frameworks and/or dictionaries;arranging the plurality of location entities into a hierarchy of location descriptors, the arranging including: inserting a descriptor of each of the plurality of location entities derived from an address field of each of the plurality of location entities as a leaf node in a tree of location descriptors;determining that at least two leaf nodes refer to a same instance if the at least two leaf nodes share a same location descriptor and if the same location descriptor is shared by a number of descendant nodes of a same parent, the number exceeding a first threshold number; andcombining the at least two leaf nodes, the combining including retaining one of the at least two leaf nodes at a lowest level in the hierarchy in which a number of occurrences of the at least two leaf nodes exceeds a second threshold number;determining whether one of the plurality of location entities is a spatial outlier based at least in part on determining whether a number of one or more other location entities within a predetermined distance of the one of the plurality of location entities exceeds a third threshold number, the one or more other location entities and the one of the plurality of location entities sharing a location descriptor;in response to determining that the one of the plurality of location entities is the spatial outlier, deleting the one of the plurality of location entities; andsending an update to the location search server such that the plurality of location entities on the location search server reflects the deletion of the spatial outlier. 20.
