<H1><A NAME="required results">REQUIRED RESULTS</A></H1>
<P>The particular fields returned in a result are backend- (search
engine-) dependent. However, all search engines are required to
return a url and title. (This list may grow in the future.)</P>

<P>
<H2><A NAME="new">new</A></H2>
<P>To create a new WWW::SearchResult, call</P>
<PRE>
$result = new WWW::SearchResult();</PRE>
<P>
<H2><A NAME="url">url</A></H2>
<P>Returns the primary URL. Note that there may be a list of urls, see
also methods <CODE>urls</CODE> and <CODE>add_url</CODE>. Nothing special is guaranteed
about the primary URL other than that it is the first one returned by
the back end.</P>
<P>Every result is required to have at least one URL.</P>
<P>
<H2><A NAME="urls">urls</A></H2>
<P>Return a reference to an array of urls.
There is also a primary URL (<CODE>url</CODE>).
See also <CODE>add_url</CODE>.</P>
<P>
<H2><A NAME="add_url">add_url</A></H2>
<P>Add a URL to the list.</P>
<P>
<H2><A NAME="related_urls, add_related_url, related_titles, add_related_title">related_urls, add_related_url, related_titles, add_related_title</A></H2>
<P>Analgous to urls, these functions provide lists of related URLs
and their titles. These point to things the search engine thinks
you might want.</P>
<P>
<H2><A NAME="title, description, score, change_date, index_date, size, raw">title, description, score, change_date, index_date, size, raw</A></H2>
<P>Set or get attributes of the result.</P>
<P>None of these attributes is guaranteed to be provided by
a given backend. If an attribute is not provided
its method will return <A HREF="../../../lib/Pod/perlfunc.html#item_undef"><CODE>undef</CODE></A>.</P>
<P>Typical contents of these attributes:</P>
<DL>
<DT><STRONG><A NAME="item_title">title</A></STRONG><BR>
<DD>
The title of the hit result (typically that provided by the 'TITLE'
HTML tag).
<P></P>
<DT><STRONG><A NAME="item_description">description</A></STRONG><BR>
<DD>
A brief description of the result, as provided (or not) by the search engine.
Often the first few sentences of the document.
<P></P>
<DT><STRONG><A NAME="item_source">source</A></STRONG><BR>
<DD>
Source is either the base url for this result (as listed on the search
engine's results page) or another copy of the full url path of the
result. It might also indicate the source site address where the
resource was found, for example, 'http://www.cnn.com' if the search
result page said ``found at CNN.com''.
<P>This value is backend-specific; in fact very few backends set this
value.</P>
<P></P>
<DT><STRONG><A NAME="item_score">score</A></STRONG><BR>
<DD>
A backend specific, numeric score of the search result.
The exact range of scores is search-engine specific.
Usually larger scores are better, but this is no longer required.
See normalized_score for a backend independent score.
<P></P>
<DT><STRONG><A NAME="item_normalized_score">normalized_score</A></STRONG><BR>
<DD>
SORRY, THIS IS NOT IMPLEMENTED.
<P>This is intended to be a backend-independent score of the search
result. The range of this score is between 0 and 1000. Higher values
indicate better quality results.</P>
<P></P>
<DT><STRONG><A NAME="item_change_date">change_date</A></STRONG><BR>
<DD>
When the result was last changed.
<P></P>
<DT><STRONG><A NAME="item_index_date">index_date</A></STRONG><BR>
<DD>
When the search engine indexed the result.
<P></P>
<DT><STRONG><A NAME="item_size">size</A></STRONG><BR>
<DD>
The approximate size of the result, in bytes. This is only an
approximation because search backends often report the size as
``18.4K''; the best we can do with that number is return it as the value
of 18.4 * 1024.
<P></P>
<DT><STRONG><A NAME="item_raw">raw</A></STRONG><BR>
<DD>
The raw HTML for the entire result. Raw should be exactly the raw
HTML for one entry. It should not include list or table setup
commands (like ul or table tags), but it may include list item or
table data commands (like li, tr, or td). Whether raw contains a list
entry, table row, br-separated lines, or plain text is search-engine
dependent. In fact, many backends do not even return it at all.
