Bug 1265227

Description of problem:

I had a bug relative to 'tripleo::packages', therefor I looked for that directly, but I believe the usage of '::' made the search engine crash providing stack trace.

Version-Release number of selected component (if applicable):
Current version - not sure which one it is.

How reproducible:
Always

Steps to Reproduce:
1. Access https://bugzilla.redhat.com/buglist.cgi?no_redirect=1&quicksearch=tripleo%3A%3Apackage
Or
1. Search anything of the form: test::test

Actual results:
Couldn't search for the bugs containing that string

Expected results:
Could search for this type of string by escaping those type of caracters

Additional info:

Stack trace:
An error occurred while performing a database operation:
