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);
IMPORTANT:

The Range algorithm is experimental only and not intended for public use. It is subject to breaking changes. This API is part of the experimental Queryable Encryption API and may be subject to breaking changes in future releases.

New in version 1.24.0.

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

To query with a RangePreview 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 RangePreview 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>"]}]

Parameters

Returns

Returns true if successful. Returns false and sets error otherwise.
