Elasticsearch分析器配置

Question

我在弹性搜索中运行术语统计，我得到了结果：

 "tevez's": {
               "doc_freq": 165,
               "ttf": 245,
               "term_freq": 1,
               "tokens": [
                  {
                     "position": 722,
                     "start_offset": 4077,
                     "end_offset": 4084
                  }
               ],
               "score": 9.041515

如何告诉elasticsearch考虑tevez's和tevez

是一样的吗？

我也得到：

"benched": {
               "doc_freq": 130,
               "ttf": 140,
               "term_freq": 1,
               "tokens": [
                  {
                     "position": 757,
                     "start_offset": 4292,
                     "end_offset": 4299
                  }
               ],
               "score": 9.278306

我如何告诉elasticsearch考虑benched和bench是否相同？
