I needed a solution for a problem with my smartphone concerning a terrible battery draining. I searched on Google in my language but didn't find anything helpful. By using a Cross-Language Search Engine, I found that a blogger somewhere in Poland had already a solution to my problem but his post was written in a language I didn’t know. So, I just "machine-translated" his post to understand the gist of the content. I realised then that it was exactly what I was looking for, and I asked a polish coleague to translate for me the whole content.
