You can choose a builtin or saved query as a starting point for filtering
results by selecting it with `queryKey`. If you don't specify a `queryKey`,
the query will start with no constraints.

For example, many applications have builtin queries like `"active"` or
`"open"` to find only active or enabled results. To use a `queryKey`, specify
it like this:

```lang=json, name="Selecting a Builtin Query"
{
  ...
  "queryKey": "active",
  ...
}
```

The table below shows the keys to use to select builtin queries and your
saved queries, but you can also use **any** query you run via the web UI as a
starting point. You can find the key for a query by examining the URI after
running a normal search.

You can use these keys to select builtin queries and your configured saved
queries:
