摘要： Disclosed is a technique for indexing data. A token is received. It is determined whether a data field associated with the token is a fixed width. When the data field is a fixed width, the token is designated as one for which fixed width sort is to be performed. When the data field is a variable length, the token is designated as one for which a variable width sort is to be performed.

摘要： Disclosed is a method, system, and program for handling redirects in documents. At least one equivalence class that includes documents that are connected through a redirect. Cycles for each equivalence class are detected, wherein documents in a cycle are marked so that they are not indexed. Incomplete chains for each equivalence class are detected, wherein documents in an incomplete chain are marked so that they are not indexed. A representative for each equivalence class is selected.

摘要： A holistic twig join method with optimal cursor movement is disclosed. The method in one aspect minimizes the number of cursor moves by looking more globally at the query's state to determine which cursor to move next and making virtual moves where a physical move is not needed. The method in another aspect reduces the number of cursor moves by skipping over nodes that do not need to be output.
摘要翻译：公开了一种具有最佳光标移动的整体树枝连接方法。一方面的方法通过在查询的状态下更全面地查看光标移动的数量来最小化以确定哪个光标移动到下一个并且进行不需要物理移动的虚拟移动。另一方面的方法通过跳过不需要输出的节点来减少光标移动的数量。

摘要： Provided are a method, system, and article of manufacture for searching documents for ranges of numeric values. Document identifiers for documents are accessed, wherein the documents include at least one value that is a member of a set of values. A number of posting lists are generated. Each posting list is associated with a range of consecutive values within the set of values and includes document identifiers for documents including at least one value within the range of consecutive values associated with the posting list, and wherein each document identifier is associated with one value in the set of values included in the document identified by the document identifier. The generated posting lists are stored, wherein the posting lists are used to process a query on a range of values within the set of values.

摘要： A system and method for querying a stream of XML data in a single pass using standard XQuery expressions. The system comprises: an expression parser that receives a query and generates a parse tree; a SAX events API that receives the stream of XML data and generates a stream of SAX events; an evaluator that receives the parse tree and stream of SAX events and buffers fragments from the stream of SAX events that meet an evaluation criteria; and a tuple constructor that joins fragments to form a set of tuple results that satisfies the query for the stream of XML data.
摘要翻译：一种使用标准XQuery表达式在单次传递中查询XML数据流的系统和方法。该系统包括：表达式解析器，其接收查询并生成解析树; 一个SAX事件API，它接收XML数据流并生成一个SAX事件流; 接收SAX事件的解析树和流的评估器，并从满足评估标准的SAX事件流中缓冲片段; 以及连接片段以形成一组满足XML数据流查询的元组结果的元组构造函数。
