Besides Google and Bing there are others alternatives machines search, such as 2Lingual, with which you can find content and facilities not available on Google.
Although the Google Search καθώς και άλλες search engines support multiple languages, none can be searched at the same time two languages. In none but the 2Lingual.
What's interesting about 2Lingual is the fact that the core search technology is Google Search, so you won't lose quality, but you'll get something extra that the standalone doesn't offer tool of Google.
Users can choose from a wide range of languages and get results for two different search languages side by side. Of course it also supports the Greek language. From our brief experience with this tool, we can say with certainty that it works quite well, so we have no problem recommending it.
