<p>A phrase search is a method of searching a database for subsets of the database that are relevant to an input query. First, a number of relational models os subsets of a database are provided. A query is then input. The query can include one or more sequences of terms. Next, a relational model of the query is created. The relational model of the query is then compared to each one of the relational models of subsets of the database. The identifiers of the relevant subsets are then output.</p> |
