    pub bloom_filter: Option<Vec<u16>>,
    pub hmac_256: Option<String>,

    pub ste_vec: Option<Vec<EqlCiphertextBody>>,
}

Struct that can carry values of all possible cryptographic searchable encrypted metadata (SEM) types.

This structure contains various SEM types that enable different query operations on encrypted data. Each SEM type supports specific query patterns:

• ORE indexes enable range queries (greater than, less than, etc.)
• Bloom filters enable approximate membership testing
• HMAC/Blake3 enable exact match queries
• SteVec enables vector/array containment queries

Serialization

• All fields are optional and null values are not serialized
• This allows the database to store only the indexes actually needed for each field
• The JSON format matches the EQL specification for database storage

Fields

• ore_block_u64_8_256 - ORE block index for 64-bit integers (serialized as “ob”)
• bloom_filter - Bloom filter for approximate match queries (serialized as “bf”)
• hmac_256 - HMAC-SHA256 hash for exact matches (serialized as “hm”)
• selector - Selector value for deterministic encryption (serialized as “s”)
• blake3 - Blake3 hash for exact matches (serialized as “b3”)
• ore_cllw_u64_8 - ORE CLLW fixed-width index for 64-bit values (serialized as “ocf”)
• ore_cllw_var_8 - ORE CLLW variable-width index (serialized as “ocv”)
• ste_vec_index - Structured encryption vector index for containment queries (serialized as “sv”)

Fields

ore_block_u64_8_256: Option<Vec<String>>

SEM term for the 64-bit Block ORE scheme (serialized as “ob”).

bloom_filter: Option<Vec<u16>>

Bloom filter for approximate match queries (serialized as “bf”).

hmac_256: Option<String>

HMAC-SHA256 hash for exact matches (serialized as “hm”).

selector: Option<String>

Selector to field-selection in an SteVec (for Json queries).

blake3: Option<String>

Blake3 hash for exact matches in a structured encryption vector AKA SteVec (serialized as “b3”).

ore_cllw_u64_8: Option<String>

ORE CLLW fixed-width scheme for 64-bit values in a structured encryption vector AKA SteVec (serialized as “ocf”).

ore_cllw_var_8: Option<String>

ORE CLLW variable-width scheme used for string comparison in an SteVec (serialized as “ocv”)

ste_vec: Option<Vec<EqlCiphertextBody>>

Structured encryption vector (STE) scheme for supporting containment queries and a subset of JSON-style operations (serialized as “sv”).
