/** Combination of the values of the facet.
 *  
 * When multiple values are allowed they can be combined differently:
 * 

 *   OR
 *   This is equivalent to join results of queries filtering on each facet value.
 *   
For example, one can filter on red and blue ties.
 *   Red ties, blue ties and red+blue ties will be present in result set.
 *   AND
 *   This is equivalent to intersect results of queries filtering on each facet value.
 *   
For example, one can filter on red and blue ties.
 *   Ties only red or blue will not be present in result set.
