Enum elastic_types::string::mapping::IndexOptions

pub enum IndexOptions {
    Docs,
    Freqs,
    Positions,
    Offsets,
}

The index_options parameter controls what information is added to the inverted index, for search and highlighting purposes.

Variants

Docs

Only the doc number is indexed. Can answer the question Does this term exist in this field?

Freqs

Doc number and term frequencies are indexed. Term frequencies are used to score repeated terms higher than single terms.

Positions

Doc number, term frequencies, and term positions (or order) are indexed. Positions can be used for proximity or phrase queries.

Offsets

Doc number, term frequencies, positions, and start and end character offsets (which map the term back to the original string) are indexed. Offsets are used by the postings highlighter.
