An unfiltered image search engine may display images without filtering results for objectionable or illegal content. It may also refer to an image search engine that does not attempt to profile the user and alter search results based on that profile.
Some search engines have a safe search feature that automatically attempts to filter out potentially objectionable results from image searches. However, even if the safe search feature is voluntarily disabled, the search engine may still automatically screen out illegal and very disturbing content, such as child pornography and executions. Google and other search engines also build an automated profile of users and filter results based on what they think the user wants to see. A completely unfiltered search engine may not do these things.
