A promotion may also be used to demote documents to fall to a lower rank position. Such promotions are called demotions.

A promotion contains a collection of promoted items sharing the same boost value. When the boost value is positive, the subset of items in a result set that react on a promotion (a matching promoted expression, promoted location, or promoted document) are boosted so the result set items may reach a higher rank position in the result set. When the boost value is negative, the subset of items that react on a promotion may fall to a lower rank position. A promotion is either a globally valid search setting or related to a keyword; a keyword promotion. A keyword promotion only takes effect if the search query matches the keyword. Such a match is found if the query contains the keyword or if one of the registered keyword synonyms equals the query.
