excerpt(text, phrase, options = {})
Instance Public methods
Extracts an excerpt from text that matches the first instance
of phrase. The :radius option expands the excerpt
on each side of the first occurrence of phrase by the number
of characters defined in :radius (which defaults to 100). If
the excerpt radius overflows the beginning or end of the text,
then the :omission option (which defaults to ââ¦â) will be
prepended/appended accordingly. Use the :separator option to
choose the delimitation. The resulting string will be stripped in any case.
If the phrase isn't found, nil is returned.
