Class cSearchResult

CONTENIDO API - SearchResult Object

This object ranks and displays the result of the indexed fulltext search. If you are not comfortable with this API feel free to use your own methods to display the search results. The search result is basically an array with article ID's.

If $search_result = $search->searchIndex($searchword, $searchwordex);

use object with

$oSearchResults = new cSearchResult($search_result, 10);

$oSearchResults->setReplacement('<span style="color:red">', '</span>'); // html-tags to emphasize the located searchwords

$num_res = $oSearchResults->getNumberOfResults(); $num_pages = $oSearchResults->getNumberOfPages(); $res_page = $oSearchResults->getSearchResultPage(1); // first result page foreach ($res_page as $key => $val) { $headline = $oSearchResults->getSearchContent($key, 'HTMLHEAD'); $first_headline = $headline[0]; $text = $oSearchResults->getSearchContent($key, 'HTML'); $first_text = $text[0]; $similarity = $oSearchResults->getSimilarity($key); $iOccurrence = $oSearchResults->getOccurrence($key); }

Methods summary
`public`	# `__construct( array $search_result, integer $result_per_page, cDb $oDB = NULL, boolean $bDebug = false )` Compute ranking factor for each search result and order the search results by ranking factor NOTE: The ranking factor is the sum of occurences of matching searchterms weighted by similarity (in %) between searchword and matching word in the article. TODO: One can think of more sophisticated ranking strategies. One could use the content type information for example because a matching word in the headline (CMS_HEADLINE[1]) could be weighted more than a matching word in the text (CMS_HTML[1]).
