你不需要示例化一个以上的HighlightBuilder。HighlightBuilder使用模式生成器，要应用更多的点，只需在同一个HighlightBuilder示例中添加“字段”。

String[] indices = {"index1", "index2", "index3"};

// Build the search request
SearchRequest searchRequest = new SearchRequest(indices);

// Build the search source
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
searchSourceBuilder.query(QueryBuilders.matchQuery("field", "search term"));

// Build highlighters for each index
HighlightBuilder highlightBuilder = new HighlightBuilder().field("field1").field("field2").field("field3");

// Add highlighters to the search source for each index
searchSourceBuilder.highlighter(highlightBuilder);

// Set the search source on the search request
searchRequest.source(searchSourceBuilder);

最好使用HighlightBuilder和requireFieldMatch示例（在代码中使用dpend）

// Define the indices to search on
String[] indices = {"index1", "index2", "index3"};

// Build the search request
SearchRequest searchRequest = new SearchRequest(indices);

// Build the search source
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
searchSourceBuilder.query(QueryBuilders.matchQuery("field", "search term"));

// Build a highlighter for each index
HighlightBuilder highlightBuilder1 = new HighlightBuilder().field("field1");
HighlightBuilder highlightBuilder2 = new HighlightBuilder().field("field2");
HighlightBuilder highlightBuilder3 = new HighlightBuilder().field("field3");

// Create a map of index name to highlighter
Map<String, HighlightBuilder> highlighters = new HashMap<>();
highlighters.put("index1", highlightBuilder1);
highlighters.put("index2", highlightBuilder2);
highlighters.put("index3", highlightBuilder3);

// Add highlighters to the search request for each index
searchSourceBuilder.highlighter(highlighters);

// Set the search source on the search request
searchRequest.source(searchSourceBuilder);

您可以为每个索引创建一个HighlightBuilder，并使用highlighter方法将其添加到搜索请求中，该方法接受Map〈String，HighlightBuilder〉
