Where are instructions on how to use the angled brackets in regular expressions?

Question

For example, instructions that would make sense of this regex search term:

<*ing

The angled brackets do not seem to be mentioned in the help section on regular expressions. Thanks!

Hey, if you want to learn about regular expressions there are a few programs out there, such as RegexBuddy. They also let you test the regular expressions against a data set you provide, so you can see what works and what doesn't.

FileLocator Pro uses the Boost regular expression engine. The details for the syntax can be found here:
http://www.boost.org/doc/libs/1_63_0/libs/regex/doc/html/boost_regex/syntax/perl_syntax.html

Here's a quote from that page:

The following escape sequences match the boundaries of words:

< Matches the start of a word.
> Matches the end of a word.
\b Matches a word boundary (the start or end of a word).
\B Matches only when not at a word boundary.
