# Extracts an excerpt from +text+ that matches the first instance of +phrase+.
|
||||
# The <tt>:radius</tt> option expands the excerpt on each side of the first occurrence of +phrase+ by the number of characters
|
||||
# defined in <tt>:radius</tt> (which defaults to 100). If the excerpt radius overflows the beginning or end of the +text+,
|
||||
# then the <tt>:omission</tt> option (which defaults to "...") will be prepended/appended accordingly. The resulting string
|
||||
# will be stripped in any case. If the +phrase+ isn't found, nil is returned.
