There exists a strong need for better search engines that extract information that is minimal in quantity but maximal in usefulness. The conventional keyword-based search is advantageous in that it is basically domain-independent and computationally efficient. However, it is also often pointed out that "keywords" are not sufficient to specify the search condition and preference of the user. This paper presents a sentence-based search method where the search condition and preference are given by a sequence of sample sentences. This approach poses syntactic constraints on the relationship among keywords, and the contextual constraints on the sentences. We show an application of our search method to an assembly minutes system.
