How do I block image search which contains certain words?

To block an image search using the Cisco Web Security appliance, we need to configure regular expressions
that match the image search URLs. This can be done via GUI −> Web Security Manager > Custom URL
Category > Advanced > Regular Expressions.

Here are some samples for blocking images with the search terms planes or trains or automobiles−

## AOL
search\.aol\.com/aol/image\?.*&query=([^&]*[\+])?(planes|trains|automobiles)[\+&]
search\.aol\.com/aol/image\?.*&query=([^&]*[\+])?(planes|trains|automobiles)$

## Google for different countries
images\.google\.co(m|\.[^/]{1,6})/images\?.*(\+|q=)(planes|trains|automobiles)[\+&]
images\.google\.co(m|\.[^/]{1,6})/images\?.*(\+|q=)(planes|trains|automobiles)$

## Yahoo
images\.search\.yahoo\.com/search/images.*(\+|p=)(planes|trains|automobiles)[\+&]
images\.search\.yahoo\.com/search/images.*(\+|p=)(planes|trains|automobiles)$

## MSN for different countries
search\.msn\.co(m|\.[^/]{1,6})/images/results\.aspx\?.*(\+|q=)(planes|trains|automobiles)[\+&]
search\.msn\.co(m|\.[^/]{1,6})/images/results\.aspx\?.*(\+|q=)(planes|trains|automobiles)$

## Yahoo Japan
image\−search\.yahoo\.co\.jp/search\?.*(\+|p=)(planes|trains|automobiles)[\+&]
image\−search\.yahoo\.co\.jp/search\?.*(\+|p=)(planes|trains|automobiles)$
