+Adding Query Search Params:
+
+Using the `query` option, you can add search parameters to your query. This option is extended from [unjs/ohmyfetch](https://github.com/unjs/ohmyfetch) and is using [ufo](https://github.com/unjs/ufo) to create the URL. Objects are automatically stringified.
+
+```ts
+const param1 = ref('value1')
+const { data, pending, error, refresh } = await useFetch('https://api.nuxtjs.dev/mountains',{
+    query: { param1, param2: 'value2' }
+})
+```
+Results in `https://api.nuxtjs.dev/mountains?param1=value1&param2=value2`
