摘要： Embodiments herein prevent or mitigate attacks on inverse query engines by providing safe mode routines that allow for the acceptance of third party messages and/or query expressions, as well as prevent trusted sources from accidental attacks. The mitigations fall into two categories: compile-time and runtime. Compile-time mitigations prevent query expressions from being accepted and compiled that are susceptible to known attacks. For example, the complexity of query expressions may be limited to functions with linear runtimes; constant memory usage; or ones that do not create large strings. Further, language constructs for the criteria in the query expression may not allow for nested predicates complexities. Runtime mitigations, on the other hand, monitor the data size and processing lengths of messages against the various query expressions. If these runtime quotas are exceeded, an exception or other violation indication may be thrown (e.g., abort), deeming the evaluation as under attack.
摘要翻译：这里的实施例通过提供允许接受第三方消息和/或查询表达式的安全模式例程，以及防止可信源来自意外攻击来防止或减轻对反向查询引擎的攻击。缓解分为两类：编译时和运行时。编译时缓解阻止查询表达式受到已知攻击的接受和编译。例如，查询表达式的复杂性可能限于具有线性运行时的函数; 不断的内存使用; 或者不创建大字符串的那些。此外，查询表达式中的条件的语言结构可能不允许嵌套谓词的复杂性。另一方面，运行缓解则根据各种查询表达式监视消息的数据大小和处理长度。如果超出这些运行时配额，可能会抛出异常或其他违规指示（例如，中止），将评估视为受到攻击。

摘要： Provided herein are optimizations for an instruction tree of an inverse query engine. Secondary sub-expression elimination trees are provided, which are data structures configured to include nodes that allow for temporary variables that hold processing context or state for idempotent fragments of query expression(s). As such, when sub-paths for a query expression are processed against a message, the processing context may be stored within nodes of one or more sub-expression elimination trees. The next time this same fragment is processed, regardless of where it appears within the instruction tree, the data structure is accessed to identify and retrieve the state information such that the idempotent fragment is only calculated or evaluated once.

摘要： Example embodiments provide a high performance navigator configured to lightly touch on the elements or input of a message, without necessarily having to build an entire tree structure for each input within the message. In addition, as portions of the inputs are identified as requiring further details, only those stub nodes representing that particular input will be created; thus avoiding the setup cost associated with loading an entire tree. Other example embodiments also provide for other optimizations such as reducing the class types of node allocations needed for navigating a particular message. For instance, a single class is defined that holds enough fields to store all of the information needed for numerous input nodes. Further, these common node structures can simultaneously generate as an array that further allows for more efficient navigation of the inputs.
摘要翻译：示例性实施例提供了被配置为轻轻触摸消息的元素或输入的高性能导航器，而不必为消息内的每个输入构建整个树结构。另外，由于输入的部分被识别为需要进一步的细节，所以仅将形成表示该特定输入的那些存根节点; 从而避免与加载整个树相关的设置成本。其他示例实施例还提供其他优化，例如减少用于导航特定消息所需的节点分配的类类型。例如，定义了一个类，它保存足够的字段来存储许多输入节点所需的所有信息。此外，这些公共节点结构可以同时生成为进一步允许输入的更有效的导航的阵列。

摘要： Embodiments provide for select indexing, which uses an array to simultaneously construct output sets for instructions that operate on input nodesets with common axes. During evaluation of a message against an instruction tree, when a branching node with a large “splay” is iterated over, rather than iterating over an input nodeset with a common axis once per branch, the select indexing described herein iterates over the nodeset once in total. More specifically, the select index data structure includes an array of empty node sets for instructions that both, branch from a branching node, and evaluate input nodes that share a common axis. Identifiers for the input nodeset are compared to indices within the select index, and matches for the input nodes are added to the corresponding nodeset for the appropriate instruction. The results of the evaluation may then be passed to the branches of the select instructions for further processing.
摘要翻译：实施例提供了选择索引，其使用阵列来同时构造用于在具有公共轴的输入节点集上操作的指令的输出集合。在针对指令树的消息评估期间，当遍历具有大“splay”的分支节点时，而不是遍历具有每个分支的公共轴的输入节点集，这里所述的选择索引在该节点集上一次遍历总。更具体地，选择索引数据结构包括用于从分支节点分支并且评估共享公共轴的输入节点的指令的空节点集的阵列。将输入节点集的标识符与选择索引中的索引进行比较，并将输入节点的匹配添加到相应的节点集中以获取适当的指令。然后可以将评估结果传递给选择指令的分支用于进一步处理。

摘要： In an inverse query environment, exemplary embodiments describe a set of shortcut keys that can be used to augment common query functions making it easier for developers to write query expressions. Further, these shortcut keys can be used to more efficiently execute equivalent functionality of the common query expressions, without evaluating large query strings against the message. In addition, embodiments described herein allow for automatic versioning of query functions, allowing for more maintainability of query expression sets. For example, a custom query library is provided with information about standard query functions based on industry wisdom of those functions most commonly referenced and/or versioned. Developers can use abbreviated query function shortcut keys in executing equivalent functionality of the lengthier string values for common query functions. The custom query library can also be modified with up-to-date information as industry changes are needed, thereby automatically maintaining the query expressions.

摘要： At least one implementation described herein relates to evaluating queries structured according to a first format against one or more objects structured according to a second, different format without serializing the object. Typically, evaluating an XML (eXtensible Markup Language) query against a CLR (Common Language Runtime) object required serializing the CLR object and deriving an XML construct from the serialized data. The query is then be evaluated against the XML construct. In the described implementations, significant system resources are realized by creating an infoset model that maps properties of an object to an object infoset. The query is then evaluated using the infoset to locate object values and, thus, no serialization is required. Dynamically generated IL is used and re-used to efficiently perform subsequent evaluation steps on similar queries.

摘要： In a network providing for electronic commerce, a computer system provides a user with access to a set of electronic commerce pages, category pages and databases for locating products electronically. To locate products electronically, the user performs a search using multiple words. The search terms in the search request are converted to canonical phonetic forms, and a phonetic keyword search based on the canonical phonetic forms is performed. The phonetic keyword search is then used to generate search results.
