我在add user autocomplete插件中找到了以下类。它扩展了普通的searcha并允许“*”；

示例：$wp\\u user\\u search=new A2B\\u user\\u查询（数组（\'search\'=>$s.*\'）；

A2B\\u User\\u Query类扩展了WP\\u User\\u Query{/***@请参见WP\\u User\\u Query：：get\\u search\\u sql（）*/函数get\\u search\\u sql（$string，$cols，$wild=false）{$string=esc\\u sql（$string）；

    // Always search all columns
    $cols = array(
        \'user_email\',
        \'user_login\',
        \'user_nicename\',
        \'user_url\',
        \'display_name\'
    );

    // Always do \'both\' for trailing_wild
    $wild = \'both\';

    $searches = array();
    $leading_wild = ( \'leading\' == $wild || \'both\' == $wild ) ? \'%\' : \'\';
    $trailing_wild = ( \'trailing\' == $wild || \'both\' == $wild ) ? \'%\' : \'\';
    foreach ( $cols as $col ) {
        if ( \'ID\' == $col )
            $searches[] = "$col = \'$string\'";
        else
            $searches[] = "$col LIKE \'$leading_wild" . like_escape($string) . "$trailing_wild\'";
    }

    return \' AND (\' . implode(\' OR \', $searches) . \')\';
}
