About this parameter

Controls if and how query words are interpreted as prefixes.

Options:

  • prefixLast: Only the last word is interpreted as a prefix (default behavior).

  • prefixAll: All query words are interpreted as prefixes. This option is not recommended, as it tends to yield counterintuitive results and has a negative impact on performance.

  • prefixNone: No query word is interpreted as a prefix. This option is not recommended, especially in an instant search setup, as the user will have to type the entire word(s) before getting any relevant results.
