"""
Create a node
### Parameters
- **children**: One or more sub-conditions. These can be additional
`intersect`, `disjunct`, `union`, `optional`, or any other `Node`
type.
The semantics of multiple conditions are dependent on the type of
query. For an `intersection` node, this amounts to a logical AND,
for a `union` node, this amounts to a logical `OR`.
- **kwparams**: key-value parameters. Each key is the name of a field,
and the value should be a field value. This can be one of the
following:
- Simple string (for text field matches)
- value returned by one of the helper functions
- list of either a string or a value
### Examples
Field `num` should be between 1 and 10
```
intersect(num=between(1, 10)
```
Name can either be `bob` or `john`
```
union(name=("bob", "john"))
```
Don't select countries in Israel, Japan, or US
```
disjunct_union(country=("il", "jp", "us"))
```
