比较简单，但是修改同义词库需要重启es。

1、同义词词库

准备一个同义词词库，每行一个同义词词组，例子 elasticsearch/config/analysis/syno.dic

  1. 西红柿,番茄,tomato
  2. 马铃薯,土豆

2、配置分词器

  1. PUT /people_v3
  2. {
  3.   "settings": {
  4.     "number_of_shards": 1,
  5.     "number_of_replicas": 0,
  6.     "analysis": {
  7.       "filter": {
  8.         "my_synonym_filter": {
  9.           "type": "synonym",
  10.           "synonyms_path" : "analysis/syno.dic"
  11.         }
  12.       },
  13.       "analyzer": {
  14.         "my_synonyms": {
  15.           "tokenizer": "ik_max_word",
  16.           "filter": [
  17.             "lowercase",
  18.             "my_synonym_filter"
  19.           ]
  20.         }
  21.       }
  22.     }
  23.   }
  24. }

效果：

  1. GET people_v3/_analyze
  2. {
  3.   "text": "我爱土豆",
  4.   "analyzer": "my_synonyms"
  5. }
  7. {
  8.   "tokens": [
  9.     {
  10.       "token": "我",
  11.       "start_offset": 0,
  12.       "end_offset": 1,
  13.       "type": "CN_CHAR",
  14.       "position": 0
  15.     },
  16.     {
  17.       "token": "爱",
  18.       "start_offset": 1,
  19.       "end_offset": 2,
  20.       "type": "CN_CHAR",
  21.       "position": 1
  22.     },
  23.     {
  24.       "token": "土豆",
  25.       "start_offset": 2,
  26.       "end_offset": 4,
  27.       "type": "CN_WORD",
  28.       "position": 2
  29.     },
  30.     {
  31.       "token": "马铃薯",
  32.       "start_offset": 2,
  33.       "end_offset": 4,
  34.       "type": "SYNONYM",
  35.       "position": 2
  36.     }
  37.   ]
  38. }
