7. The method of claim 1 , further comprising:

receiving a subsequent geographical search request;

identifying the geographical region based on the subsequent geographical search request;

selecting the second map data source from a subset of the plurality of map data sources, the subset not including the first map data source; and

receiving a third set of candidate geographical locations for the target geographical location from the second map data source.

8. The method of claim 1 , further comprising:

receiving map data source information associated with a target map data source;

modifying the plurality of selection rules to indicate an allocation of geographical search requests to the target map data source;

determining that the target map data source provides map data associated with a target geographical region; and

modifying a plurality of map data sources associated with the target geographical region to include the target map data source.

9. The method of claim 1 , wherein the quality level is based on a latency of receiving the first set of candidate geographical locations from the first map data source being below a second threshold value.

10. The method of claim 1 , wherein the second map data source associated with a second geographical region larger than the geographical region and including the geographical region.

11. The method of claim 10 , wherein the target geographical location is located within a predetermined distance outside of the geographical region, and further comprising:

providing at least one candidate geographical location of the first set along with the second set to the client device for display.

12. A method comprising:

receiving a geographical search request from a client device of a user of a service arrangement system corresponding to a target geographical location;

identifying a selection rule of a plurality of selection rules indicative of allocations of geographical search requests to a plurality of map data sources;

receiving a first set of candidate geographical locations for the target geographical location from a first map data source of the plurality of map data sources based on the geographical search request;

using one or more processors, determining a first quality level of the first set of candidate geographical locations;

using the one or more processors, selecting a second map data source of the plurality of map data sources in response to determining that the first quality level is below a threshold value, the second map data source selected based on the selection rule;

receiving a second set of candidate geographical locations for the target geographical location from the second map data source based on the geographical search request;

using the one or more processors, determining a second quality level of the first set of candidate geographical locations; and

providing one or more candidate geographical locations of the second set of candidate geographical locations to the client device for display in response to determining that the second quality level is greater than the threshold value.

13. The method of claim 12 , wherein the quality level is based on a latency of receiving the first set of candidate geographical locations from the first map data source being below a second threshold value.

14. A computer program product comprising a non-transitory computer readable storage medium having instructions encoded thereon that, when executed by one or more processors, cause the one or more processors to:

receive a geographical search request from a client device of a user of a service arrangement system corresponding to a target geographical location;

identify a geographical region based on the geographical search request;

identify a selection rule of a plurality of selection rules indicative of allocations of geographical search requests to a plurality of map data sources associated with the geographical region

select a first map data source of a plurality of map data sources based on the selection rule, each of the plurality of map data sources associated with the geographical region;

receive a first set of candidate geographical locations for the target geographical location from the first map data source based on the geographical search request;

using one or more processors, determine a quality level of the first set of candidate geographical locations;

select a second map data source of the plurality of map data sources in response to determining that the quality level is below a first threshold value, the second map data source selected based on the selection rule;

receive a second set of candidate geographical locations for the target geographical location from the second map data source based on the geographical search request; and

provide one or more candidate geographical locations of the second set of candidate geographical locations to the client device for display.

15. The non-transitory computer readable storage medium of claim 14 , having further instructions that when executed by the one or more processors cause the one or more processors to determine another quality level of the second set of candidate geographical locations, wherein providing the second set of candidate geographical locations to the client device is in response to determining that the another quality level is greater than the first threshold value.

16. The non-transitory computer readable storage medium of claim 14 , wherein the geographical search request includes a sequence of characters input by the user, the quality level is based on whether the number of characters in the sequence of characters is greater than a second threshold value.

17. The non-transitory computer readable storage medium of claim 14 , having further instructions that when executed by the one or more processors cause the one or more processors to:

receive feedback in response to providing the one or more candidate geographical locations; and

modify at least one of the plurality of selection rules based on the feedback.

18. The non-transitory computer readable storage medium of claim 14 , having further instructions that when executed by the one or more processors cause the one or more processors to:

receive a subsequent geographical search request;

identify the geographical region based on the subsequent geographical search request;

select the second map data source from a subset of the plurality of map data sources, the subset not including the first map data source; and

receive a third set of candidate geographical locations for the target geographical location from the second map data source.

19. The non-transitory computer readable storage medium of claim 14 , wherein the plurality of selection rules indicate, for each map data source of the plurality of map data sources, a proportion of geographical search requests from client devices of users of the service arrangement system to allocate to the corresponding map data source.

20. The non-transitory computer readable storage medium of claim 14 , having further instructions that when executed by the one or more processors cause the one or more processors to:
