One search term, or a topic as `id:` followed by a Knowledge Graph id (`id:/m/02vqfm`). A single term may contain a comma; send it as one parameter value.

Place: a country code (`US`, `DE`), a subdivision (`US-CA`, `DE-BY`) or an empty string for worldwide. Lowercase input is accepted and normalised to uppercase. Default: `US`.

Category id from the categories endpoint. `0` (the default) means all categories.

Property to search: `web` (default), `images`, `news`, `youtube` or `shopping`.

Interface language, as Google calls `hl` (`en-US`, `de`, `ja`, `ar`). It localises names, dates and type text; it does not translate the queries.

Time range: `now 1-H`, `now 4-H`, `now 1-d`, `now 7-d`, `today 1-m`, `today 3-m`, `today 12-m`, `today 5-y`, `all`, or a custom `YYYY-MM-DD YYYY-MM-DD` range (hourly `YYYY-MM-DDTHH` is accepted).
