java整合spring-boot-starter-data-elasticsearch4.0.0实现多字段搜索，排序，高亮显示

网上找了很多种方案一直调试不正确，最后自己琢磨半天才调试通过 ，代码实现效果图如下：

附上代码：

    @Override
    public PageResult fullTextSearch(FullTextParam param) {
        Integer pageNum = param.getPageNum();
        Integer pageSize = param.getPageSize();
        String[] attrType = param.getAttrType();
        String[] docType = param.getDocType();
        String searchKey = param.getSearchKey();
        Pageable pageable = PageRequest.of(pageNum - 1, pageSize);

        //es的分页是从0开始的
        NativeSearchQueryBuilder searchQueryBuilder = new NativeSearchQueryBuilder();
        searchQueryBuilder.withPageable(pageable);
        BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery();
        //按照分类进行过滤查询
        if (attrType != null && attrType.length > 0) {
            //过滤精准匹配，用作查询具体的分类
            boolQueryBuilder.must(QueryBuilders.termsQuery("attr_type", attrType));
        }
        //档案类型过滤
        if (docType != null && docType.length > 0) {
            //过滤精准匹配，用作查询具体的分类
            boolQueryBuilder.filter(QueryBuilders.termsQuery("doc_type", docType));
        }
        boolQueryBuilder.must(QueryBuilders.existsQuery("title"));


        if (StringUtils.isNotBlank(searchKey)) {
            boolQueryBuilder.should(QueryBuilders.multiMatchQuery(searchKey, "title", "summary"));
        }
        FunctionScoreQueryBuilder functionScoreQueryBuilder = QueryBuilders.functionScoreQuery(boolQueryBuilder)
                .scoreMode(FunctionScoreQuery.ScoreMode.SUM)
                .setMinScore(1);
        searchQueryBuilder.withQuery(functionScoreQueryBuilder);
        // 设置是否按查询匹配度排序

        //设置高亮
        HighlightBuilder highlighter = new HighlightBuilder();
        //设置三要素
        highlighter.field("title");
        highlighter.field("summary");
        //设置前后缀标签
        highlighter.preTags("");
        highlighter.postTags("");
        //加载已经设置好的高亮配置
        searchQueryBuilder.withHighlightBuilder(highlighter);
        // 过滤查询
//        searchQueryBuilder.withFilter(boolQueryBuilder);
        //========================过滤查询 结束=====================================
        searchQueryBuilder.withSort(SortBuilders.scoreSort().order(SortOrder.DESC));//相关性排序
        searchQueryBuilder.withSort(SortBuilders.fieldSort("data_time").order(SortOrder.DESC));//时间排序

        // 搜索条件构造器构建：NativeSearchQuery
        NativeSearchQuery searchQuery = searchQueryBuilder.build();

        log.info("DSL:{}", searchQuery.getQuery());

        SearchHits searchHits = elasticsearchRestTemplate.search(searchQuery, SummaryIndex.class);
        if(searchHits.getTotalHits()<=0){
            return null;
        }
        List summaryIndices = new ArrayList<>();
        List> result = searchHits.getSearchHits();
        result.forEach(
                res -> {
                    SummaryIndex index = res.getContent();
                    Map> highlightFields = res.getHighlightFields();
                    List highlight = highlightFields.get("title");
                    if (highlight != null && highlight.size() > 0) {
                        StringBuffer buffer = new StringBuffer();
                        for (String s : highlight) {
                            buffer.append(s);
                        }
                        index.setTitle(buffer.toString());
                    }
                    List summaryHighlight = highlightFields.get("summary");
                    if (summaryHighlight != null && summaryHighlight.size() > 0) {
                        StringBuffer buffer = new StringBuffer();
                        for (String s : summaryHighlight) {
                            buffer.append(s);
                        }
                        index.setSummary((String[]) Arrays.asList(buffer.toString()).toArray());
                    }
                    summaryIndices.add(index);
        });

        com.github.pagehelper.Page page = new com.github.pagehelper.Page(pageNum, pageSize);
        //为Page类中的total属性赋值
        long total = searchHits.getTotalHits();
        page.setTotal(total);
        //从链表中截取需要显示的子链表，并加入到Page
        page.addAll(summaryIndices);
        //以Page创建PageInfo
        PageInfo pageInfo = new PageInfo<>(page);
        return PageUtils.getPageResult(pageInfo);
    }
