Current Internet search engines find documents by matching queries to documents, then present the closest matches to the user. Such searching is often ineffective. Another technique for searching, which with current algorithms is not feasible for large text collections such as the Web, is to browse vocabularies and view phrases in the contexts in which they are used. The aim of this project is to make wider use of phrases in retrieval, by developing new phrase-based querying algorithms and investigating how users can use phrase indexes to find documents. The outcome will be new, efficient methods for exploring the Internet.

当前的互联网搜索引擎通过将查询与文档匹配来查找文档，然后将最接近的匹配呈现给用户。 这种搜索往往是无效的。 另一种搜索技术是浏览词汇表并在使用词汇表的上下文中查看短语，但目前的算法对Web等大型文本集合不可行。 该项目的目的是通过开发新的基于短语的查询算法和研究用户如何使用短语索引来查找文档，从而在检索中更广泛地使用短语。 其结果将是探索互联网的新的、有效的方法。
