Struct JsonIndexerOptions
pub struct JsonIndexerOptions {
pub prefix: String,
pub term_filters: Vec<TokenFilter>,
pub array_index_mode: ArrayIndexMode,
pub mode: SteVecMode,
}Expand description
Configuration for a JsonIndexer.
JsonIndexerOptions controls how a JSON document is tokenized and indexed.
It can be constructed directly, or derived from a column configuration via
TryFrom<&column::IndexType>.
Fields§
§prefix: StringDomain-separation prefix mixed into the keyed MAC used to tokenize JSON paths and values.
Two indexers with the same key but different prefixes will produce
disjoint token spaces, so the prefix must match between the indexing
side and the query side for results to be comparable. In practice this
is set to a stable column identifier (e.g. "cs_ste_vec_v1").
term_filters: Vec<TokenFilter>Term filters applied to every string leaf node before indexing.
Filters run in order against each string value (e.g. Downcase,
Stemmer, Stop). If any filter rejects a term by returning None,
the string is replaced with Value::Null rather than indexed. To match
at query time, the same filters must be applied to the query plaintext.
array_index_mode: ArrayIndexModeControls which selectors are emitted for array entries.
See ArrayIndexMode — ALL emits item, positional, and wildcard
selectors for each element; narrower modes (ITEM, POSITION,
WILDCARD, NONE) reduce index size at the cost of which query
shapes are supported.
mode: SteVecModeSelects the STE-vec encoding scheme used by this indexer.
See SteVecMode — the mode selects the orderable-term primitive:
Standard (the default) uses ORE, Compat uses OPE. Selectors are
always Blake3-keyed and term-side MACs are always HMAC-SHA256 in both
modes. Indexes produced under different modes are not cross-comparable,
so the indexing side and the query side must agree on the mode for
results to match.
