The problem is that we are talking to the models/gemini-2.5-flash-native-audio-preview-09-2025 in the Belarusian language, and we want to use the googleSearch grounding. And it appears that the model generates the search query in Belarusian as well (although there’s no way to prove this, we experimented and this assumption seems correct). In this case, the quality of the search is very low because there’s not much information available in Google search in the Belarusian language. So, we’d like the model to use search grounding, providing the search query in a different language (Russian or English).
We tried setting this in the model’s sys prompt, but it doesn’t help at all.
Does anybody know if it is possible to achieve?
Alternatively, is it possible to use the google search manually, wrapping it into my own tool, not the grounding? This way, I have better control over the function arguments.
