How to hightlight Text in Solr Search using @Highlight annotation in Repository

Question

I have tried to highlight the text using:

@Highlight(prefix="<strong>",postfix="</strong>")

Like this:

@Query("articletype:?0")
@Highlight(prefix="<strong>",postfix="</strong>")
ON SOME METHOD

But this doesn't work.

I have even tried to highlight by passing the query as an attr in @Highlight . But that didn't work.

Please suggest how to use @Highlight with @Query to highlight the content.

1.

@Query("field_name:?0")
@Highlight(prefix="<strong>",postfix="</strong>")
public HighlightPage<YOUR_ENTITY_CLASS> yourSomeMethod(String textToBeSearched);

2.

HighlightPage listSolrPage =solrRepository.yourSomeMethod(textToBeSearched);

3.

 for (HighlightEntry<YOUR_ENTITY_CLASS> he : listSolrPage.getHighlighted()) {
            for (Highlight highlight : he.getHighlights()) {
                    // Each highlight might have multiple occurrences within the description
                    StringBuilder sb = new StringBuilder();
                    for (String snipplet : highlight.getSnipplets()) {                      
                        // snipplet contains the highlighted text
                        slf4jLogger.debug(snipplet);
                        sb.append(snipplet + "");
                    }
            }
        }
