qstringrequired
Parameter defines the search query. You can use anything that you would use in a regular Baidu Maps search: a type of place, a business, a brand, or a landmark (e.g., `咖啡` (coffee), `酒店` (hotels), `星巴克` (Starbucks), or `故宫` (the Forbidden City)). Without `c`, the query can include the city to search in (e.g., `上海 咖啡` for coffee in Shanghai).
