Problems with the search function!

[Brasilian]

Some users have reported me malfunction of the thread tilte search box!
By inserting in the box, for example, the search key Perlite the browser returns not load the page, and this URL: http: //127.0.0.1/? stext = perlite
Enter more keys instead seems to be working properly!

Thanks in advance for any tips or troubleshooting!
