A human can easily and clearly see that the more important word in the user query is WinRAR, but Google Alerts returns even those random search results which contain only the word 'released'.
Secondly, I never wrote the word 'buy', but Google's oversmart algorithms automatically introduce this word [in the background] when they see 'Deutsche Bank'. It isn't necessary that if someone says Deutsche, then it must be about investment buy/sell decisions. These are failed results by Google.
