我想要执行精确的单词匹配和部分单词/子串匹配.例如,如果我搜索"男士剃须刀",那么我应该能够在结果中找到"男士剃须刀".但是在我搜索"en的剃须刀"的情况下,我也应该能够在结果中找到"男士剃须刀".我使用以下设置和映射:

索引设置:

PUT /my_index
{
    "settings": {
        "number_of_shards": 1, 
        "analysis": {
            "filter": {
                "autocomplete_filter": { 
                    "type":     "edge_ngram",
                    "min_gram": 1,
                    "max_gram": 20
                }
            },
            "analyzer": {
                "autocomplete": {
                    "type":      "custom",
                    "tokenizer": "standard",
                    "filter": [
                        "lowercase",
                        "autocomplete_filter" 
                    ]
                }
            }
        }
    }
}

映射:

PUT /my_index/my_type/_mapping
{
    "my_type": {
        "properties": {
            "name": {
                "type":            "string",
                "index_analyzer":  "autocomplete", 
                "search_analyzer": "standard" 
            }
        }
    }
}

插入记录:

POST /my_index/my_type/_bulk
{ "index": { "_id": 1            }}
{ "name": "men's shaver" }
{ "index": { "_id": 2 …
