Abstract: In one embodiment, a method comprises receiving a search request; generating a search query based on the search request, the search query including a logical expression, the logical expression including a logical operator that operates on multiple operands, at least one of the operands including an optional search constraint and an associated weight; searching a data store to identify a set of objects matching the search query, the set of objects including a subset of objects satisfying the logical expression, each object in the subset satisfying at least one of the operands, for each operand that includes an optional search constraint, at least a proportion of the objects in the subset satisfying the optional search constraint, the proportion determined based on the associated weight; and sending instructions for presenting a search-results page, the search-results page including search results corresponding to the objects in the identified set of objects.

Abstract: In one embodiment, a method comprises, by a computer system, receiving a search term, determining a search constraint for a search query, and generating a search query. The search query includes the search term and the search constraint. The search query requires that at least a first number of search results that are returned in response to the search query match both the search term and the search constraint. The search query permits at least a second number of the search results to match only the search term. The computer system provides the search query for a search against a store of data.

Abstract translation: 在一个实施例中，一种方法包括由计算机系统接收搜索项，确定搜索查询的搜索约束，以及生成搜索查询。 搜索查询包括搜索项和搜索约束。 搜索查询要求响应于搜索查询返回的至少第一数量的搜索结果与搜索条件和搜索约束相匹配。 搜索查询允许至少第二数目的搜索结果仅匹配搜索项。 计算机系统为搜索数据提供搜索查询。
