.search(search_type, search_terms, link_text) ⇒ Object

Every plugin must contain a #search method that takes 3 arguments:

  • ‘search_type` will contain the !search trigger that was used (minus the !)

  • ‘search_terms` will include everything that came after the !search

  • ‘link_text` will contain the text that will be used for the linked

text portion of the link. This can usually remain untouched but must be passed back at the end of the function.
