1. Search terms problem:
SimpleTags use of the full text of the search, as long as the article contains the keyword matching, which can lead to large errors match, I modify it only match of the headlines.
Open file simple-tags\inc\simple-tags.admin.php, in line 1466, replace:
$search_sql = "AND ( (post_title LIKE '%{$search}%') OR (post_content LIKE '%{$search}%') )";to:
$search_sql = "AND ( (post_title LIKE '%{$search}%') OR (post_title LIKE '%{$search}%') )";2. Untagged only problem:
When blog have large numbers of the article, the untagged only function will return errors, I change some of original code in the SQL statement , greatly improving the efficiency of search and speed.
Open file simple-tags\inc\simple-tags.admin.php, in line 1475, replace:
$p_id_used = $wpdb->get_col("
SELECT DISTINCT term_relationships.object_id
FROM {$wpdb->term_taxonomy} term_taxonomy, {$wpdb->term_relationships} term_relationships, {$wpdb->posts} posts
WHERE term_taxonomy.taxonomy = 'post_tag'
AND term_taxonomy.term_taxonomy_id = term_relationships.term_taxonomy_id
AND term_relationships.object_id = posts.ID
AND posts.post_type = '{$type}'");
$filter_sql = 'AND ID NOT IN ("'.implode( '", "', $p_id_used ).'")';to:
$p_id_used = "SELECT DISTINCT term_relationships.object_id
FROM {$wpdb->term_taxonomy} term_taxonomy, {$wpdb->term_relationships} term_relationships, {$wpdb->posts} posts
WHERE term_taxonomy.taxonomy = 'post_tag'
AND term_taxonomy.term_taxonomy_id = term_relationships.term_taxonomy_id
AND term_relationships.object_id = posts.ID
AND posts.post_type = '{$type}'";
$filter_sql = 'AND ID NOT IN ('.$p_id_used.')';
