EXPAND Numbers in SELECT Statements

Using EXPAND Numbers in Multiple-Term SELECT Statements

You can SELECT an E or R number together with other search terms or set numbers in the same statement.

You can also include a group of E or R numbers in a longer SELECT statement. Enter the number or the range of numbers as a search term, using spacing and parentheses as necessary for correct processing.

Using Proximity Operators with EXPAND Numbers

You can SELECT a single E or R number in proximity to another term or set. SELECT the E or R number followed by the proximity operator and the search term or set number.

You can also SELECT a group of E or R numbers in proximity to another term or set. If you SELECTed a range using OR, the group must be placed within parentheses in the search statement. If you SELECTed a range with a colon, no parentheses are necessary.

• To link R-numbered descriptors to a subheading using the (L) operator:
