Robert:
If search string has html entities, then do not proceed with search.

Well, its very hard to define if query string has HTML entities or
not? For example, do you consider following string has HTML entities?

b = "hello world and so what; and < and there we go >"

dunno yes and no, but if your answer is yes, and string `b` HAS HTML
entities then:

require 'cgi'

escaped_html = CGI::escapeHTML(b)
if escaped_html != b
 # string contains html entities
end

if you want a strict validation of HTML tags, and whether query is a
valid HTML, then hpricot may help.
