Multi-search and multi-task in search

Map multi-search architecture that enables users to multi task on the mapping engine website. A card interaction model enables the creation of new cards for new tasks and from which users can retrieve previous results without needing to redo the search task. One or more cards can be retrieved by scrolling through and selecting the desires card(s). Point-of-interest (POI) capabilities of the architecture introduce different POI colors, POI sizes, and a decay model which enables users to differentiate between different sets of results and furthermore, enables users to see the proximity of different sets of results. The POI system enables differentiated POI sets for different sets of search results and/or detail cards. 地图多元搜索架构使得用户能够在地图引擎网站上执行多任务。卡片交互模型实现了针对新任务创建新卡片，并且用户可以从卡片中检索之前的结果，而不需要重新执行搜索任务。可通过从头至尾滚动卡片并选择所需卡片的方式检索个或多个卡片。架构的兴趣点(POI)能力引入不同的POI颜色、POI尺寸、和衰减模型，该衰减模型使得用户能够在不同的结果集之间进行区分，而且，使得用户能够查看不同结果集的邻近度。POI系统实现了针对不同的搜索结果集和/或细节卡片的可区分的POI集。
