The highlightPostTag parameter defines the HTML tag inserted after the matching text in highlighted attributes. It works in combination with highlightPreTag, which marks the beginning of the highlighted portion.

​
Usage

  • Set an empty string ("") to fallback to the default tag.
  • To turn off highlighting, remove the searchable attribute with the attributesToHighlight parameter.

​
Examples

​
Set default tag

Current API clients

var response = await client.SetSettingsAsync(
  "INDEX_NAME",
  new IndexSettings { HighlightPostTag = "</em>" }

settings.HighlightPostTag = "";

index.SetSettings(settings);

Current API clients
