Public methods
There are none defined here; see WWW::Search.
Private methods
native_setup_search
This private method does the heavy lifting after you call native_query().
native_retrieve_some
This private method does the heavy lifting of fetching and parsing web pages.
How does it work?
"native_setup_search" is called before we do anything. It initializes our private variables (which all begin with underscores) and sets up a URL to the first results page in "{_next_url}".
"native_retrieve_some" is called (from "WWW::Search::retrieve_some") whenever more hits are needed. It calls the LWP library to fetch the page specified by "{_next_url}". It parses this page, appending any search hits it finds to "{cache}". If it finds a ``next'' button in the text, it sets "{_next_url}" to point to the page for the next set of results, otherwise it sets it to undef to indicate we're done.
