    Hey,

    is it possible you can add a feature, which bans bots which do a lot of queries on the search engine? Or which get banned, if they do 5 10 clicks in 1 minute or like that.

    They search like this:

    ???1+1?20170519 ???????????
    ?????????? pv&?????/??????? pv&?????/??

    Would be a nice feature!

    Hi,

    There is already a rate-limit feature in the premium version of NinjaFirewall.

    But if you just want to block search queries containing several question marks, you can use the .htninja file:

    <?php
/*
 +===================================================================+
 | NinjaFirewall optional configuration file                         |
 |                                                                   |
 | See: http://nintechnet.com/ninjafirewall/wp-edition/help/?htninja |
 +===================================================================+
*/

// Block search requests containing at least 4 consecutive "?" signs:
if ( isset( $_GET['s'] ) && strpos( $_GET['s'], '????' ) !== FALSE ) {
   return 'BLOCK'; // reject it
}

    Use regular expression to check the unicode character, for instance, Han for Chinese:

    
if ( isset( $_GET['s'] ) && preg_match( '/\p{Han}/u', $_GET['s']) ) {
   return 'BLOCK'; // reject it
}

    Cyrillic should do for Russian. See http://php.net/manual/en/regexp.reference.unicode.php
