一个模块，在发布页面或其他内容后更新搜索索引。已针对 Elasticsearch 6.1.1 进行更新和成功测试。

此说明有助于您设置 Elasticsearch。

在 Elasticsearch 端点创建索引和映射的初步步骤

第 1 步：创建具有设置的索引

curl -XPUT 'http://host:9200/myindex/' -H 'Content-type: application/json' -d '
{
  "settings": {
    "index": {
      "analysis": {
        "filter": {
          "stemmer": {
            "type": "stemmer",
            "language": "german"
          },
          "autocompleteFilter": {
            "max_shingle_size": "6",
            "min_shingle_size": "2",
            "type": "shingle",
            "filler_token": "",
            "output_unigrams" : true
          },
          "stopwords": {
            "type": "stop",
            "stopwords": [
              "aber","als","am","an","auch","auf","aus","bei","bin","bis","bist","da","dadurch","daher","darum","das","daß","dass","dein","deine","dem","den","der","des","dessen","deshalb","die","dies","dieser","dieses","doch","dort","du","durch","ein","eine","einem","einen","einer","eines","er","es","euer","eure","für","hatte","hatten","hattest","hattet","hier","hinter","ich","ihr","ihre","im","in","ist","ja","jede","jedem","jeden","jeder","jedes","jener","jenes","jetzt","kann","kannst","können","könnt","machen","mein","meine","mit","muß","mußt","musst","müssen","müßt","nach","nachdem","nein","nicht","nun","oder","seid","sein","seine","sich","sie","sind","soll","sollen","sollst","sollt","sonst","soweit","sowie","und","unser","unsere","unter","vom","von","vor","wann","warum","was","weiter","weitere","wenn","wer","werde","werden","werdet","weshalb","wie","wieder","wieso","wir","wird","wirst","wo","woher","wohin","zu","zum","zur","über"
            ]
          }
        },
        "analyzer": {
          "didYouMean": {
            "filter": [
              "lowercase"
            ],
            "char_filter": [
              "html_strip"
            ],
            "type": "custom",
            "tokenizer": "standard"
          },
          "autocomplete": {
            "filter": [
              "lowercase",
              "stopwords",
              "autocompleteFilter"
            ],
            "char_filter": [
              "html_strip"
            ],
            "type": "custom",
            "tokenizer": "standard"
          },
          "default": {
            "filter": [
              "lowercase",
              "stopwords",
              "stemmer"
            ],
            "char_filter": [
              "html_strip"
            ],
            "type": "custom",
            "tokenizer": "standard"
          }
        }
      }
    }
  }
}
'

第 2 步：在索引上创建映射

curl -XPUT 'http://host:9200/myindex/_mapping/de/' -H 'Content-type: application/json' -d '
{
  "de": {
    "properties": {
      "autocomplete": {
        "type": "text",
        "analyzer": "autocomplete",
        "fielddata": true
      },
      "content": {
        "type": "text",
        "analyzer" : "default",
        "copy_to": [
          "did_you_mean",
          "autocomplete"
        ]
      },
      "did_you_mean": {
        "type": "text",
        "analyzer": "didYouMean",
        "fielddata": true
      },
      "title": {
        "type": "text",
        "analyzer" : "default",
        "copy_to": [
          "autocomplete",
          "did_you_mean"
        ]
      }
    }
  }
}
'

第 3 步：从 Elasticsearch 包启动索引器 cronjob

Attention!!! please empty the table "papaya_search_indexer_status" before you start the indexer cronjob

如果需要删除索引

curl -XDELETE 'host:9200/myindex'

手动搜索请求

curl -XPOST 'http://host:9200/myindex/de/_search/' -d '
{
  "suggest": {
    "didYouMean": {
      "text": "*patient*",
      "phrase": {
        "field": "did_you_mean"
      }
    }
  },
  "from":0,
  "size":10,
  "query": {
    "query_string": {
      "query": "*patient* OR patient",
      "fields": ["title^2","content"]
    }
  },
  "sort" : {
        "_score" : {
            "order" : "desc"
        }
  },
  "highlight" : {
    "fragment_size" : 100,
    "number_of_fragments" : 3,
    "no_match_size": 100,
    "fields" : {
        "content" : {

        }
    }
  }
}
'

手动建议请求

curl -XPOST 'http://host:9200/myindex/de/_search/' -d '
{
  "size": 0,
  "aggregations": {
    "didYouMean": {
      "terms": {
        "field": "didYouMean",
        "order": {
          "_count": "desc"
        },
        "include": {
          "pattern": "patient.*"
        }
      }
    },
    "autocomplete": {
      "terms": {
        "field": "autocomplete",
        "order": {
          "_count": "desc"
        },
        "include": {
          "pattern": "patient.*"
        }
      }
    }
  }
}
