search:snippet(
   $result as node(),
   $cts-query as schema-element(cts:query),
   [$options as element(search:transform-results)?]
) as element(search:snippet)

Summary

This function extracts matching text from the result node based on options, and returns the matches wrapped in a containing node, with highlights tagged.

Parameters
result A node from which to pull matching snippets from.
cts-query A serialized and annotated cts:query, typically the result of a call to search:parse.
options Options to define the search grammar and control the search. See description for $options for the function search:search. Note that you cannot specify the apply attribute on the transform-results option with search:snippet; to use a different snippetting function, use search:search or search:resolve instead.
