*Place searches:

Nearby Search	returns a list of nearby places based on a user's location.
Text Search	returns a list of nearby places based on a search string, eg. "Pizza".
Radar Search	returns a large list of places within a specified search radius, but with less detail than either Nearby Search or Text Search.
Place Details Requests	return more detailed information about a specific place, including user reviews.

*Place search pagination(分页): accessing additional results, By default, each place search returns up to 20 results per query. However, each search can return as many as 60 results; PlaceSearchPagination; hasNextPage; nextPage()

*Search for up to 200 places with Radar Search:The Radar Search returns more results than a Nearby Search or Text Search, but the results contain fewer fields. You can callPlacesService.getDetails() to get more information about any of the places in the response.
