Searching forum - possible bug?

[solid]

Hello.

I've tried to search the forum for the word "shell:" without quotes.
I only got the message: visit the www.ghisler.com.

After repeating the search, the forum was inaccessible for a while.

Is this a intended behavior, a bug or a blacklisted search?

Confirmed.

Confirmed - the forum was inaccesible for maybe 10 minutes. Changing browser or rebooting the system did not help.

2petermad Thank you for confirming.

This is probably some (overly sensitive) forum protection that bans the connecting/offending IP for a few minutes to avoid abuse. Just a guess though.

I guess that it was some security hole in PHP in the past, and some bots possibly still try to abuse that hole. As the colon is ignored by the search engine (try to search for "example:"), it's better to use wildcard and search for "shell*" (with asterisk).
