BACKGROUND: Many months ago I created three custom search engines and two word clouds. These latter are used to track visitor search interest and Grammar Captive's ability to match it. Unfortunately, someone is now abusing my search engines and filling those fields of my database set aside to track search input. The result of this malicious effort is word clouds that no longer perform their task. While investigating the mess I have realized two important short-comings of my search engines that I must address: The Sanitization/Filtering of Search Input -- In order to produce meaningful word clouds I must clean my search input of non-meaningful characters such as ', ", /, [, (, ", etc. As Further, as my search engines are capable of handling multilingual input, I must be able to handle unwanted characters in a variety of languages. Span Prevention - I must be able to prevent visitors from abusing my search engines and thus destroying Grammar Captive's ability to track and analyze true visitor interest. I do not see myself as resolving these two problems easily and would be grateful for any advice that would push in in the direction of successful resolution. Roddy PS. If you would like to view the damage that has occurred, go to the Grammar Captive website and examine the word clouds found under Visitor Profile/Word Clouds in the navigation bar.
