Boolean Datatype
Boolean fields accept JSON true and false values, but can also accept
strings which are interpreted as either true or false, but you have to
explicitly use the _type boolean. The two following examples are equivalent:
UPDATE /bank/1
{
    "isPublished": true
}UPDATE /bank/1
{
    "isPublished": {
      "_value": "true",
      "_type": "boolean"
    }
}When using strings, you can use any of the following and it gets interpreted
as either true or false:
- "true",- "t", ,- "1"->- true
- "false",- "f",- "0"->- false
Parameters
The following parameters are accepted by Boolean fields:
| _value | The value for the field. (Only used at index time). | 
| _index | The mode the field will be indexed as: "none","field_terms","field_values","field_all","field","global_terms","global_values","global_all","global","terms","values","all". (The default is"field_all"). | 
| _slot | The slot number. (It’s calculated by default). | 
| _prefix | The prefix the term is going to be indexed with. (It’s calculated by default) |
