es2.4.0分组错误

es.2.4.0使用聚合实现分组统计功能：按公司名称统计，例如公司名称“禅城一中队”， 统计结果为：禅，277,；城，277,；一，200；中，277；队，277。这种统计结果谁想要！！！！！！！！希望大侠帮忙看看，问题出在哪里。源码如下：
QueryBuilder queryBuilder = QueryBuilders.matchPhraseQuery("compName","禅城一中队");
TermsBuilder termsBuilder = AggregationBuilders.terms("aggCompany")
.field("compName");
SearchRequestBuilder srb = client
.prepareSearch(IndexEnum.FIRE.getName())
.setTypes(DocType.EQUIP.getName())
.setSearchType(SearchType.DFS_QUERY_THEN_FETCH)
.setSize(1000)
.setExplain(true);
srb.setQuery(queryBuilder);
srb.addAggregation(termsBuilder);
SearchResponse response = srb.execute().actionGet();
Map<String, Aggregation> companyMap = response.getAggregations()
.asMap();
StringTerms companyTerms = (StringTerms) companyMap.get("aggCompany");
logger.info("company agg size:" + companyTerms.getBuckets().size());
Iterator<Bucket> companyBucketIt = companyTerms.getBuckets().iterator();
long i = 0;
while (companyBucketIt.hasNext())
{
Bucket companyBucket = companyBucketIt.next();
logger.info("i:" + i++ + "**" + companyBucket.getKeyAsString()
+ " 单位有 " + companyBucket.getDocCount() + " 条数据");
}
