B/ prefixed before query will use traditional boolean search to find document matches. Example: B/"CDMA wireless device" Query will result in all documents that contain the phrase "CDMA wireless device"
R/ prefixed before query will re-rank the result set according to relevancy to the query. Can use patent number to indicate full text of patent. Example: R/6311189 Query will result in the result set to be re-ranked according to relevancy to the full text of USPTO patent 6311189
Can combine B/ and R/ into one query where the result set will contain all documents that contain the search phrase after B/ and the result set will be re-ranked according to relevancy of the search phrase after R/. Example: B/CDMA and R/20040114468 Query will result in all documents that contain "CDMA" and the result set will be re-ranked according to relevancy to the USPTO patent application 2004/0114468

Any of the above search field operators may be chained to form a more complete query using AND, OR, ANDNOT
