pub fn highlight(
text: &str,
query_terms: &[String],
analyzer: Option<&Analyzer>,
opts: &HighlightOptions,
) -> AnalysisResult<String>Expand description
Wrap matched query terms in text with the configured tags.
analyzer is optional: when supplied, both the query terms and
the source text are run through the same pipeline so stemming /
lower-casing / accent folding agree. When omitted, ASCII
lower-case is used instead.
