摘要： A method for performing a search of a plurality of documents for similarity to a query word includes retrieving a first document, and determining a number of occurrences of the at least one query word in the first document. Then, a next document is retrieved and a number of occurrences of the at least one query word in the next document is determined. The steps are repeated until each of the plurality of documents have been retrieved, and the number of occurrences of the at least one query word has been determined in each of the plurality of documents. The query word can include a plurality of query words, all of which are searched in each document, in turn, rather than being searched word by word in the whole collection of documents. The documents are then ranked according to the number of occurrences of the query words determined in each document, and a list of documents is produced according to the document ranking.
摘要翻译：执行与查询词相似的多个文档的搜索的方法包括检索第一文档以及确定第一文档中的至少一个查询词的出现次数。然后，检索下一个文档，并确定下一个文档中的至少一个查询词的出现次数。重复这些步骤，直到已经检索到多个文档中的每一个，并且已经在多个文档的每一个中确定了至少一个查询词的出现次数。查询词可以包括多个查询词，所有这些查询词都是在每个文档中搜索，而不是在整个文档集合中逐句搜索。然后根据在每个文档中确定的查询词的出现次数来排列文档，并且根据文档排名产生文档列表。
