Optimal query execution strategy chosen by the planner.

Variants

Literal

Fast path: literal string search with pre-computed trigrams.

Fields

pattern: Vec<u8>

Raw search bytes to match against.

trigrams: Vec<Trigram>

Set of trigrams extracted from the pattern.

regex: Regex

Pre-compiled regex equivalent to the literal.

RegexWithLiterals

Regex with extractable literal sub-strings.

Fields

regex: Regex

Pre-compiled user regex.

required_trigram_sets: Vec<Vec<Trigram>>

Per-literal required trigram sets (AND across sets).

CaseInsensitive

Case-insensitive indexed search. Each group = case variants for one trigram position. Executor UNIONs within groups, INTERSECTs across.

Fields

regex: Regex

Pre-compiled case-insensitive regex.

trigram_groups: Vec<Vec<Trigram>>

Per-position trigram groups (union within, intersect across).

FullScan

No literals extractable — full scan fallback.

Fields

regex: Regex

Pre-compiled regex to run against every file.

Trait Implementations
