MONGOC_CLIENT_ENCRYPTION_ENCRYPT_EXPRESSION(3) libmongoc MONGOC_CLIENT_ENCRYPTION_ENCRYPT_EXPRESSION(3)

SYNOPSIS

bool
mongoc_client_encryption_encrypt_expression (

mongoc_client_encryption_t *client_encryption,
const bson_t *expr,
mongoc_client_encryption_encrypt_opts_t *opts,
bson_t *expr_out,
bson_error_t *error);


Added in version 1.24.0.

Encrypts a Match Expression or Aggregate Expression to query a range index.

To query with a Range encrypted payload, use a mongoc_client_t <> configured with mongoc_auto_encryption_opts_t <>. The mongoc_auto_encryption_opts_t <> may be configured to bypass query analysis with mongoc_auto_encryption_opts_set_bypass_query_analysis() <>. The mongoc_auto_encryption_opts_t <> must not be configured to bypass automatic encryption with mongoc_auto_encryption_opts_set_bypass_auto_encryption() <>.

To query with a Range payload, expr must be one of the following forms:

1.
A Match Expression of the following form:

// $gt may also be $gte. $lt may also be $lte.
// Can include one of $gt/$gte/$lt/$lte. It is not required to include both.
{"$and": [{"<field>": {"$gt": "<value1>"}}, {"<field>": {"$lt": "<value2>" }}]}


2.
An Aggregation Expression of this form:

// $gt may also be $gte. $lt may also be $lte
// Can include one of $gt/$gte/$lt/$lte. It is not required to include both.
{"$and": [{"$gt": ["<fieldpath>", "<value1>"]}, {"$lt": ["<fieldpath>", "<value2>"]}]
