重复的Magento搜索词攻击

Question

We are recording an extraordinarily high number of searches for a specific search term:- "biscru" or "Ticru" (63,000 times in the past 2 months). The apache log is showing these requests as coming from Googles servers but I find this hard to believe and suspect the IP address is being spoofed.

Apache Log Example:-

rawliving.eu:66.249.72.227 - - [06/Jul/2013:01:25:09 +0100]
"GET /catalogsearch/result/index/?cat=47&dir=desc&limit=25&mode=list&order=event_date&p=6
&q=%22biscru%22+OR+%22Ticru%22
HTTP/1.1" 200 20587 "-" "Mozilla/5.0 (compatible; Googlebot/2.1;
+http://www.google.com/bot.html)"

Clearly blocking 66.249.72.227 is not a option as it is a valid google address so can anyone suggest what options we have to prevent this distortion and maybe identify where these requests are coming from and why?

Any advice gratefully received. Lee

Add this to your layout-xml definition eg local.xml

<catalogsearch_result_index translate="label">
        <reference name="head">
            <action method="setRobots"><value>NOINDEX,NOFOLLOW</value></action>
        </reference>
    </catalogsearch_result_index>
    <catalogsearch_advanced_index translate="label">
        <reference name="head">
            <action method="setRobots"><value>NOINDEX,NOFOLLOW</value></action>
        </reference>
    </catalogsearch_advanced_index>
    <catalogsearch_advanced_result translate="label">
        <reference name="head">
            <action method="setRobots"><value>NOINDEX,NOFOLLOW</value></action>
        </reference>
    </catalogsearch_advanced_result>

Check if the problem remains after a few days... or just use a robots.txt file to block the catalogsearch urls from being indexed.
