6 WWW::SearchResult - class for results returned from WWW::Search
7
9 require WWW::Search;
10 require WWW::SearchResult;
11 $search = new WWW::Search;
12 $search->native_query(WWW::Search::escape_query($query));
13 # Get first result:
14 $result = $search->next_result();
15
17 A framework for returning the results of "WWW::Search".
18
20 WWW::Search
21
23 The particular fields returned in a result are backend- (search
24 engine-) dependent. However, all search engines are required to return
25 a url and title. (This list may grow in the future.)
26
28 new
29 To create a new WWW::SearchResult, call
30
31 $result = new WWW::SearchResult();
32
33 url
34 Returns the primary URL. Note that there may be a list of urls, see
35 also methods "urls" and "add_url". Nothing special is guaranteed about
36 the primary URL other than that it is the first one returned by the
37 back end.
38
39 Every result is required to have at least one URL.
40
41 add_url
42 Add a URL to the list.
43
44 urls
45 Return a reference to the list of urls. There is also a primary URL
46 ("url").
47
48 add_related_url
49 Add a URL to the related_url list.
50
51 related_urls
52 Return a reference to the list of related urls.
53
54 add_related_title
55 Add a title to the list or related titles.
56
57 related_titles
58 Return a reference to the list of related titles.
59
60 title, description, score, change_date, index_date, size, raw
61 Set or get attributes of the result.
62
63 None of these attributes is guaranteed to be provided by a given
64 backend. If an attribute is not provided its method will return
65 "undef".
66
67 Typical contents of these attributes:
68
69 title The title of the hit result (typically that provided by the
70 'TITLE' HTML tag).
71
72 description
73 A brief description of the result, as provided (or not) by the
74 search engine. Often the first few sentences of the document.
75
76 source Source is either the base url for this result (as listed on the
77 search engine's results page) or another copy of the full url
78 path of the result. It might also indicate the source site
79 name or address whence the result came, for example, 'CNN' or
80 'http://www.cnn.com' if the search result page said "found at
81 CNN.com".
82
83 This value is backend-specific; in fact very few backends set
84 this value.
85
86 add_sources
87 Same meaning as source above, for adding sources in case there
88 are potentially multiple sources.
89
90 sources Returns a reference to the list of sources.
91
92 score A backend specific, numeric score of the search result. The
93 exact range of scores is search-engine specific. Usually
94 larger scores are better, but this is no longer required. See
95 normalized_score for a backend independent score.
96
97 normalized_score
98 This is intended to be a backend-independent score of the
99 search result. The range of this score is between 0 and 1000.
100 Higher values indicate better quality results.
101
102 This is not really implemented since no one has created an
103 backend-independent ranking algorithm.
104
105 change_date
106 When the result was last changed. Typically this is the
107 modification time of the destination web page.
108
109 index_date
110 When the search engine indexed the result.
111
112 size The approximate size of the result, in bytes. This is only an
113 approximation because search backends often report the size as
114 "18.4K"; the best we can do with that number is return it as
115 the value of 18.4 * 1024.
116
117 raw The raw HTML for the entire result. Raw should be exactly the
118 raw HTML for one entry. It should not include list or table
119 setup commands (like ul or table tags), but it may include list
120 item or table data commands (like li, tr, or td). Whether raw
121 contains a list entry, table row, br-separated lines, or plain
122 text is search-engine dependent. In fact, many backends do not
123 even return it at all.
124
125 as_HTML Convert the search result to a human-readable form, decorated
126 with HTML for pretty-printing.
127
128 Others
129 More attributes of the result. Backend-specific. Refer to the
130 documentation of each backend for details.
