NAME
WWW::SearchResult - class for results returned from WWW::Search
SYNOPSIS
require WWW::Search;
require WWW::SearchResult;
$search = new WWW::Search;
$search->native_query(WWW::Search::escape_query($query));
# Get first result:
$result = $search->next_result();
DESCRIPTION
A framework for returning the results of "WWW::Search".
SEE ALSO
WWW::Search
REQUIRED RESULTS
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.)
METHODS AND FUNCTIONS
new
To create a new WWW::SearchResult, call
$result = new WWW::SearchResult();
url
Returns the primary URL. Note that there may be a list of urls, see also methods "urls"
and "add_url". Nothing special is guaranteed about the primary URL other than that it is
the first one returned by the back end.
Every result is required to have at least one URL.
add_url
Add a URL to the list.
urls
Return a reference to the list of urls. There is also a primary URL ("url").
add_related_url
Add a URL to the related_url list.
related_urls
Return a reference to the list of related urls.
add_related_title
Add a title to the list or related titles.
related_titles
Return a reference to the list of related titles.
title, description, score, change_date, index_date, size, raw
Set or get attributes of the result.
None of these attributes is guaranteed to be provided by a given backend. If an attribute
is not provided its method will return "undef".
Typical contents of these attributes:
title The title of the hit result (typically that provided by the 'TITLE' HTML tag).
description
A brief description of the result, as provided (or not) by the search engine.
Often the first few sentences of the document.
source 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 name or address whence the result came, for example,
'CNN' or 'http://www.cnn.com' if the search result page said "found at CNN.com".
This value is backend-specific; in fact very few backends set this value.
add_sources
Same meaning as source above, for adding sources in case there are potentially
multiple sources.
sources Returns a reference to the list of sources.
score 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.
normalized_score
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.
This is not really implemented since no one has created an backend-independent
ranking algorithm.
change_date
When the result was last changed. Typically this is the modification time of the
destination web page.
index_date
When the search engine indexed the result.
size 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.
raw 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.
as_HTML Convert the search result to a human-readable form, decorated with HTML for
pretty-printing.
Others
More attributes of the result. Backend-specific. Refer to the documentation of each
backend for details.
