	 * Important: The following rules must be strictly adhered to while declaring new relevance constants or modifying the existing:
	 * 1. One or more relevance constants are used in combination to form a relevance.
	 * 2. A particular relevance constant can be added only once to form a relevance.
	 * 3. A resultant relevance (after combining all the applicable relevance constants) must be a positive number.
	 * 4. The value of R_DEFAULT is maintained at a positive value such that the sum of all the negative relevance constants
	 *    and R_DEFAULT must not be negative.
