Rex Regular EXpression Pattern Matcher


The Regular EXpression pattern matcher allows you to find those items that cannot be located with a simple wildcard search.

To invoke the REX regular expression pattern matcher within a query precede the expression with a '/' (forward slash).

Examples:


Expression                            Purpose
---------------------------------------------------------------------------
/19[789][0-9]                         Find years between 1970 and 1999

/[1-9][01][0-9]-?[0-9]{3}-=[0-9]{4}   Any USA Phone Number

/\n=\space+Clinton                    Find 'Clinton' as the first word
in a Paragraph

/\upper=\lower+\space\upper=\lower+   Proper Names without initials
like: John Smith
