    • Computerized methods and systems for performing a search utilizing a spatial index are provided. Upon receiving a search query having a zoom level component (e.g., “Italian Restaurants in Seattle”), a search is initially conducted of the zoom level tags associated with the content items in the spatial index to determine if any of the content items include a zoom level tag indicative of the zoom level component of the search query (e.g., zoom level of city for Seattle). Subsequently, only those content items satisfying the zoom level search are grouped into a primary subset, whereby the primary subset may be filtered by selecting those returned content items with location-based tags that match a location-based component of the query (e.g., Seattle, Wash.). Next, the those content items satisfying the location-based filter are grouped into a location-based subset, which are filtered according to the parsed query components (e.g., category component Italian Restaurants).
    • 提供了使用空间索引执行搜索的计算机化方法和系统。 当接收到具有缩放级别分量的搜索查询(例如,“西雅图的”意大利餐馆“)时,首先对与空间索引中的内容项相关联的缩放级别标签进行搜索,以确定是否有任何内容项包括 指示搜索查询的缩放级别组件的缩放级别标签(例如,西雅图城市的缩放级别)。 随后,仅满足缩放级别搜索的内容项目被分组为主要子集,由此可以通过选择与基于位置的标签匹配的基于位置的标签的那些返回的内容项来筛选主要子集(例如,西雅图 , 洗。)。 接下来,满足基于位置的过滤器的那些内容项被分组为基于位置的子集,其根据解析的查询组件(例如,类别组件意大利餐馆)被过滤。
