Abstract
Techniques for similarity searching are provided. Structural data in a database is searched against one or more structural queries. A desired minimum degree of similarity between the one or more queries and the structural data in the database is first specified. One or more indices are then used to exclude from consideration any structural data in the database that does not share the minimum degree of similarity with one or more of the queries.
