Struct TextFieldIndex 

pub struct TextFieldIndex {
    pub index: TextIndex,
    pub doc_to_key: BTreeMap<u32, Vec<u8>>,
    pub key_to_doc: BTreeMap<Vec<u8>, u32>,
}

Per-TEXT schema field state.

Couples one dyntext::TextIndex (trigram + bloom inverted index) with the bookkeeping the FT.* surface needs to map between user-visible document keys and the internal monotonic doc ids the text index hands back. The pairing is one TextFieldIndex per TEXT schema field per registered index; the registry initialises one for every metadata field of type MetadataFieldType::Text at FT.CREATE time.

Fields

index: TextIndex

Trigram + bloom inverted index over the field’s bytes.

doc_to_key: BTreeMap<u32, Vec<u8>>

Internal text-doc-id -> user-visible document key.

key_to_doc: BTreeMap<Vec<u8>, u32>

User-visible document key -> internal text-doc-id. Used to evict the prior entry when the same key is re-HSET-ed under an updated field value.
