摘要： A field-weighted search combines statistical information for each term across document fields in a suitably weighted fashion. Both field-specific term frequencies and field and document lengths are considered to obtain a field-weighted document weight for each query term. Each field-weighted document weight can then be combined in order to generate a field-weighted document score that is responsive to the overall query.

摘要： A query is separated into subqueries including a first subquery containing terms applicable to a first data store and a second subquery containing terms applicable to a second data store, where both data stores maintain information regarding the documents. Applying the first subquery to the first data store retrieves a first list of document identifiers associated with documents that satisfy the terms of the first subquery. The first list is combined with the second subquery to form a masked subquery, which is applied to the second data store. The masked subquery only seeks to identify document identifiers that both are included the first list and that satisfy terms of the second query. The document identifiers included in the first list may be ordered to match an order in which the document identifiers are ordered in the second data store.

摘要： Real estate ranking computation is calculated to sort real estate properties. Such computations use available information regarding real estate properties in any local markets and may help the real estate buyer to identify real estate properties with various ranked financial values. Suitably, a relatively small geographic area can be used based on the real estate buyer's specified criteria, and the real estate ranking computation is able to handle interactions among predictor variables, possesses suitable predictive confidence, and includes the capability for dynamically adjusting the underlying ranking computation as new patterns of real estate market emerge over time.

摘要： A search index structure which extends a typical composite index by incorporating an index which is optimized for fast retrieval from storage and which eliminates data which is specific to phrase searching. Other data is represented in a manner which allows it to be calculated rather than stored. Associating variable length entries with logical categories allows their length to be inferred from the category rather than stored. Using delta values between document IDs rather than the ID itself generates a compact, dense symbol set which is efficiently compressed by Huffman encoding or a similar compression method. Using an upper threshold to remove large, and thus rare, delta values from the symbol set prior to encoding further improves the encoding performance.

摘要： Technologies are described herein for providing a more efficient approach to ranking search results. An illustrative technology reduces an amount of ranking data analyzed at query time. In the technology, a term is selected, at index time, from a master index. The term corresponds to a number of documents greater than a threshold. A set of documents that includes the term is selected based on the master index. A rank is determined for each document in the set of documents that contains the term. Each document in the set of documents that contains the term is assigned to a top document list or a bottom document list based on the rank. Predefined values of at least part of the rank are stored in the top document list for documents in the top document list and are not stored in the bottom document list for documents in the bottom document list.

摘要： This disclosure describes methods and systems for searching documents in a multi-tenant hosting environment. According to embodiments, to conserve hardware resources, a plurality of documents associated with a plurality of tenants may be mapped to the same search index in the multi-tenant hosting environment. In order to search documents associated only with a single tenant in the multi-tenant hosting environment, a tenant identifier is prepended to every key stored in the search index that is associated with the plurality of documents of the single tenant. Moreover, where one document links to another document within the multi-tenant hosting environment, the link is stored in a web graph when a source tenant identifier matches a target tenant identifier for the link. According to embodiments, when conducting a search, the link is resolved only if the link is stored in the web graph.
摘要翻译： 本公开描述了用于在多租户托管环境中搜索文档的方法和系统。 根据实施例，为了节省硬件资源，可以将与多个租户相关联的多个文档映射到多租户托管环境中的相同搜索索引。 为了搜索仅在多租户托管环境中与单个租户相关联的文档，预先将租户标识符存储在与单个租户的多个文档相关联的搜索索引中存储的每个密钥。 此外，当一个文档链接到多租户托管环境中的另一个文档时，当源租户标识符与链接的目标租户标识符匹配时，链接被存储在网页图中。 根据实施例，当进行搜索时，仅当链接被存储在网络图中时才解决链接。
