Abstract: A meta-search system for performing a search over a plurality of data sources via one or more search passes, the system comprising: a search controller for: i) transmitting a search query object having a specified route which lists a plurality of query processors desired to be executed; ii) receiving data request objects from the plurality of executed query processors and transmitting the data request objects to a plurality of data collectors, each data request object being transmitted to associated data collector, iii) receiving result objects associated with the data requests from the data collectors, and iv) transmitting the result objects to a user interface for display; the plurality of query processors being executed according to the specified route to receive and process the search query object, each of the query processors enabled to generate a data request object based on the search query object and one or more data request objects generated by one or more previously executed query processors; and each of the plurality of data collectors enabled to convert a data request object received from the search controller to a request associated with an outside data source that performs a search according to the converted request, and each data collector enabled to convert a result of the search transmitted from the outside data source to a result object.

Abstract translation: 一种用于经由一个或多个搜索通过对多个数据源进行搜索的元搜索系统，所述系统包括：搜索控制器，用于：i）发送具有指定路由的搜索查询对象，所述搜索查询对象列出了期望的多个查询处理器 被执行 ii）从所述多个执行的查询处理器接收数据请求对象并将数据请求对象发送给多个数据收集器，每个数据请求对象被发送到相关联的数据收集器，iii）从数据中接收与数据请求相关联的结果对象 收集器，以及iv）将结果对象发送到用户界面进行显示; 所述多个查询处理器根据指定的路由被执行以接收和处理搜索查询对象，每个查询处理器能够基于搜索查询对象和由一个或多个数据请求对象产生的一个或多个数据请求对象使能生成数据请求对象 更先前执行的查询处理器; 并且所述多个数据收集器中的每一个使能够将从搜索控制器接收的数据请求对象转换为与根据转换的请求执行搜索的外部数据源相关联的请求，并且每个数据收集器能够将 从外部数据源发送到结果对象的搜索。
