web_search configuration help

[beyluta]

Recently the option to use web_search with Duckduckgo has been added, I would like to configure it to use duckduckgo, but I am unsure how to get it to work. I have followed the docs and added the new duckduckgo adapter, but the tool always errors out when trying to use it. I'm guessing I need a valid API key from them? But I'm not sure where to get it from or where to set it in the configs.

Hi Oli, thanks for the answer. My current configuration is mirroring the code from the docs 1:1 I tried the same config on Windows and Linux without success. But if it works for you then I think I must have misplaced files or something else is overwriting them...

My config containing the tool is here if that's helpful

still hasn't worked for me unfortunately. I will leave my minimal config here, maybe someone can help me.

return {
  {
    "olimorris/codecompanion.nvim",
    dependencies = {
      "nvim-lua/plenary.nvim",
    },
    opts = {
      interactions = {
        chat = {
          tools = {
            ["web_search"] = {
              opts = {
                adapter = "duckduckgo",
              },
            },
          },
        },
      },
      strategies = {
        cmd = {
          adapter = "ollama",
          model = "qwen3.5:latest",
        },
        chat = {
          adapter = "ollama",
          model = "qwen3.5:latest",
        },
        inline = {
          adapter = "ollama",
          model = "qwen3.5:latest",
        },
      },
    },
  },
}

My hunch is that qwen is failing to call it properly. Can you try with a non Ollama model?

I have the exact same tool config as you:

(I'm using Copilot and the free tier in this video)

I'll try it later today. Haven't had the time yet. If it is a problem with the model calling the tool, it should be fixable from our side right? Seeing as other applications can use the same model to make searches just fine.

I'm reading this because I'm also having some issues, but just at a glance it looks like your config might be wrong by using both strategies and interactions. The strategies section is obsolete, in favor of interactions. So it should look something like this:

return {
  {
    "olimorris/codecompanion.nvim",
    dependencies = {
      "nvim-lua/plenary.nvim",
    },
    opts = {
      interactions = {
        cmd = {
          adapter = "ollama",
          model = "qwen3.5:latest",
        },
        inline = {
          adapter = "ollama",
          model = "qwen3.5:latest",
        },
        chat = {
          adapter = "ollama",
          model = "qwen3.5:latest",
          tools = {
            ["web_search"] = {
              opts = {
                adapter = "duckduckgo",
              },
            },
          },
        },
      },
    },
  },
}```

Thanks, I replaced my plugin file with the content in your comment. Everything works except for the web_search so unfortunately this didn't fix my specific issue. I also tried other models such as Gemma4 and GPT-OSS but none of these Ollama local models seemed to work for web_search
