java实现ElasticSerach RestHighLevelClient 高亮，分页，范围查询

好的，关于 Java 实现 ElasticSearch RestHighLevelClient 的高亮、分页和范围查询，可以参考以下代码：

1. 高亮查询：

SearchRequest searchRequest = new SearchRequest(indexName);
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();

HighlightBuilder highlightBuilder = new HighlightBuilder();
highlightBuilder.field("fieldName");
highlightBuilder.requireFieldMatch(false);
highlightBuilder.preTags("<em>");
highlightBuilder.postTags("</em>");
searchSourceBuilder.highlighter(highlightBuilder);

searchRequest.source(searchSourceBuilder);

2. 分页查询：

SearchRequest searchRequest = new SearchRequest(indexName);
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();

searchSourceBuilder.from(0);
searchSourceBuilder.size(10);

searchRequest.source(searchSourceBuilder);

3. 范围查询：

SearchRequest searchRequest = new SearchRequest(indexName);
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();

RangeQueryBuilder rangeQueryBuilder = QueryBuilders.rangeQuery("fieldName");
rangeQueryBuilder.gt("value1");
rangeQueryBuilder.lt("value2");
searchSourceBuilder.query(rangeQueryBuilder);

searchRequest.source(searchSourceBuilder);

希望这些代码可以帮助到你。
