public class Configuration
extends java.lang.Object

This object defines rules for query computation, or rather, classes of tokens.

1. Control Token - its IDF is always 1, and it is not never excluded from query.
2. !Control Token - all tokens which are not the control ones are taken as words.
3. Default Boost - sets the default boost factor of a token. If it is set to 0, the token is not counted in the similarity value, but its restrictions are taken in mind (see required/prohibited flags).
