摘要： A tree data structure for storing strings of searchable data divided into substrings has at least one first type node that has a substring associated with it and at least one second type node that does not having a substring associated with it. A second type node is directly linked to a first type node by a fail transition. A first type node is directly linked to a second type node by a match transition. An IP address lookup system has memory for storing a tree data structure and a controller for storing and loading an incoming IP address. The system has a finite state machine having three stages including a first stage for loading the IP address and performing a length calculation, a second stage for searching the data structure to find a match, and a third stage for determine the next-hop address index.

摘要： A method for using dual indices to support query expansion, relevance/non-relevance models, blind/relevance feedback and an intelligent search interface, comprising using a computing device (89) to: access (101) an inverted index (103) to obtain an initial retrieval of results in response to a query, and to generate a rank list of the results, the results referring to information units (IUs) where the query occurs; and determine (105) a number of “N” IUs in the results that are assumed to be relevant by accessing a forward index (104); wherein the forward index (104) and inverted index (103) have pointers to locations in the IUs where terms of the query occur, and the forward index (104) retrieves a term frequency vector of the IU or a set of contexts of the IU.
摘要翻译：一种使用双重索引来支持查询扩展，相关性/非相关性模型，盲目/相关性反馈和智能搜索界面的方法，包括使用计算设备（89）来访问（101）反向索引（103）以获得响应于查询的结果的初始检索，以及生成结果的排名列表，结果参考查询发生的信息单元（IU）; 并且确定（105）通过访问前向索引（104）而被假设为相关的结果中的多个“N”IU; 其中所述前向索引（104）和反向索引（103）具有指向所述查询的条件发生的所述IU中的位置的指针，并且所述前向索引（104）检索所述IU的术语频率向量或IU的一组上下文。
