Action

  • 自问自答，如果有更好的解决方法，大家可以写在评论区

/### 临时方案1

前提

需要写一个搜索针对名字的搜索功能
名字假如是：刘德华
可以根据以下其中之一进行搜索：刘德华，liu，de，hua，刘，德，华
P.S. 只支持搜索，暂时不支持高亮

具体步骤

步骤一 create index

PUT /test_index
{
  "settings": {
    "analysis": {
      "analyzer": {
        "chinese_analyzer": {
          "tokenizer": "chinese_chars_tokenizer"
        },
        "pinyin_analyzer": {
          "tokenizer": "pinyin_tokenizer"
        }
      },
      "tokenizer": {
        "chinese_chars_tokenizer": {
          "type": "pinyin",
          "keep_first_letter": false,
          "keep_separate_first_letter": false,
          "keep_full_pinyin": false,
          "keep_original": false,
          "limit_first_letter_length": 50,
          "keep_separate_chinese": true,
          "lowercase": true
        },
        "pinyin_tokenizer": {
          "type": "pinyin",
          "keep_first_letter": false,
          "keep_separate_first_letter": false,
          "keep_full_pinyin": true,
          "keep_original": false,
          "limit_first_letter_length": 50,
          "keep_separate_chinese": true,
          "lowercase": true
        }
      }
    }
  },
  "mappings": {
    "properties": {
      "name": {
        "type": "text",
        "search_analyzer": "chinese_analyzer",
        "analyzer": "pinyin_analyzer"
