Practical Tips to Optimize Dedecms Search Function

Displaying Search Keywords and Results Dynamically

In the search results template, the [field:keyword /] tag shows the keyword entered by the user, and the [field:totalresult /] tag displays the total number of results found, enhancing interaction and clarity of the search results.

Advanced Techniques to Enhance Dedecms Search Performance

Beyond basic setup, flexible code usage can significantly improve the search experience:

Customizing Search Scope

Use the $where variable to restrict the search scope, such as searching only within a specific category. Example code:

<span class="fun">$where = "arc.typeid={$typeid}";</span>

Sorting Search Results

Sort results by publish date or click count to help users find popular or latest content quickly:

<span class="fun">$order = "arcrank DESC, senddate DESC";</span>

Keyword Highlighting

Call Dedecms’s built-in function dede_search_keywords to highlight keywords in the search results, improving readability:

<span class="fun">$content = dede_search_keywords($content, $q);</span>

Pagination of Search Results

Paginate large numbers of search results to ensure fast page loading and easier browsing:

$PageNo = isset($PageNo) ? $PageNo : 1;
$PageCount = 10;

Example: Listing Articles by Keyword Search

The following code demonstrates how to search articles with titles containing a specified keyword and paginate the results:

<?php
$q = isset($q) ? $q : '';
$where = "arc.title like '%{$q}%'" ;
$order = "pubdate DESC";
$pagesize = 10;
$PageNo = isset($PageNo) ? $PageNo : 1;
$PageCount = ceil($totalresult/$pagesize);

$arc = new Archives();
$dsql->SetQuery("SELECT * FROM `#@__archives` WHERE $where ORDER BY $order LIMIT " . ($PageNo - 1) * $pagesize . ", $pagesize");
$dsql->Execute();

while ($row = $dsql->GetObject()) {
    // Output article list content
}
?>
