摘要： Methods, systems and programming for providing query suggestions based on user's previous search query. In one example, an input including a prefix of a first query is received from a user in a user session. At least a second query that was previously received from the user in the user session is then obtained. A third query is obtained based on the second query and the prefix of the first query. One or more query suggestions are provided to the user as a response to the input. The one or more query suggestions include the third query.

摘要： Techniques are provided for automatically determining when to trigger instant search. In one technique, while a user is entering text to formulate a search query, and prior to receiving an indication that the user has completed formulation of the search query, a search assistant system determines the most popular queries that include the text the user has already entered. The search assistant system then determines whether to proactively provide, to the user, search results for the top-candidate of those completed queries. That determination may take into account factors such as whether the top-candidate qualifies as a dominant completed query, a richness metric determined for the search results for the particular completed query, and/or a satisfaction metric determined for the search results for the particular completed query. If the search assistant system determines to proactively provide search results for the particular completed query, the search results for the particular completed query are presented to the user prior to receiving any indication that the user has completed formulation of the search query.

摘要翻译： 提供了自动确定何时触发即时搜索的技术。 在一种技术中，当用户正在输入文本以制定搜索查询时，并且在接收到用户已经完成了搜索查询的制定的指示之前，搜索助理系统确定包括用户已经存在的文本的最流行的查询 输入 搜索助理系统然后确定是否主动地向用户提供搜索结果以获取那些完成的查询的顶级候选者。 该确定可以考虑诸如顶级候选人是否被认为是主要完成查询，针对特定完成查询的搜索结果确定的丰富度量度和/或针对特定完成查询的搜索结果确定的满意度度量的因素 查询。 如果搜索助理系统确定主动地为特定的完成查询提供搜索结果，则在接收到用户已经完成了搜索查询的制定的任何指示之前，向用户呈现特定完成查询的搜索结果。

摘要： In one embodiment, a portion of a search query may be obtained from a client device. A set of suggested search queries may be obtained or generated from a plurality of phrases stored in memory, where the portion of the search query matches a portion of each suggested search query in the set of suggested search queries. The set of suggested search queries may be provided to the client device. The plurality of phrases may include phrases extracted from documents published via a network.

摘要翻译： 在一个实施例中，搜索查询的一部分可以从客户端设备获得。 可以从存储在存储器中的多个短语获得或生成一组建议的搜索查询，其中搜索查询的一部分与建议的搜索查询集合中的每个建议的搜索查询的一部分相匹配。 可以将该组建议的搜索查询提供给客户端设备。 多个短语可以包括从通过网络发布的文档中提取的短语。

摘要： Method, system, and programs for providing enhanced search term suggestions. A set of incomplete search terms indicating a sequence of search terms entered may be received. It may be detected that the sequence contains a descending phase followed by an ascending phase. In response to the detection, a pair of misinput term and corresponding corrected term may be identified in the set of incomplete search terms. A probability with respect to the misinput term is a misinput of the corresponding corrected term may be determined based on a historical context. Using such a probability, an incomplete search term containing the misinput term may be corrected. One or more proposed search terms may be determined based on the corrected incomplete search term for suggestion to the user.
