Systems and methods are disclosed for efficiently searching a database including a table. The table is partitioned along a first dimension, such as latitude. Indexes in each of the partitions are built along a second dimension, such as longitude. The table may also be clustered according to an index to improve performance. When a processor receives a database query term and a starting location, the processor selects, from the table, a data partition within a first offset to the starting location along the first dimension. The processor selects, from the selected data partition, a first number of first data records related to the query term and within a second offset to the starting location along the second dimension.
