Querying and biasing

Amazon Location Service Places API offers querying and biasing options to retrieve and search location data.

Querying

A query refers to the input parameters used to retrieve and search location data. The way APIs returns results is determined by these queries types.

Biasing

The "bias position" is a location that influences search results, giving priority to places near biased position. It doesn't restrict results, but biases them toward the specified area. This feature prioritizes relevant location results when multiple places have similar names.
