|

Use a vertical bar between expressions to match either expression.  Use up to nine vertical bars, separating up to ten expressions, any of which are to be found in a line.  NOTE:  Spaces before and after the vertical bar are significant.  For example, “near | far” represents a regular-expression search for “near “ or “ far”, not “near” or “far”.

&

Use an angstrom between expressions to match both expressions.  Use up to nine angstroms, joining up to ten expressions, all of which are to be found in a line.  NOTE:  Spaces before and after the angstrom are significant.  Thus, “near & far” is not the same as “near&far”, which is probably what you want.

{ }

Use a left curly bracket paired with a right curly bracket to denote a sub-expression within the complete regular expression.  You may make and denote multiple sub-expressions within the complete regular expression.  You may refer to such sub-expressions by number if you create Replacement Expressions for Replace operations.  This denotation of a sub-expression has no effect on Find operations
