term_vector

term_vector

Term vectors contain information about the terms produced by the analysis process, including:

• a list of terms.
• the position (or order) of each term.
• the start and end character offsets mapping the term to its origin in the original string.
• payloads (if they are available) — user-defined binary data associated with each term position.

These term vectors can be stored so that they can be retrieved for a particular document.

The term_vector setting accepts:

The fast vector highlighter requires with_positions_offsets. The term vectors API can retrieve whatever is stored.

Setting with_positions_offsets will double the size of a field’s index.
