您是否尝试过完成建议？解决问题的一种方法如下：
1）创建索引：
curl -XPUT "http://localhost:9200/test_index/"
2）使用完成建议者类型创建映射：
curl -XPUT "http://localhost:9200/test_index/product/_mapping" -d'{ "product": { "properties": { "category": { "type": "string" }, "cost": { "type": "string" }, "createDate": { "type": "date", "format": "dateOptionalTime" }, "description": { "type": "string" }, "rating": { "type": "string" }, "sales": { "type": "string" }, "tags": { "type": "string" }, "title": { "type": "string" }, "suggest": { "type": "completion", "index_analyzer": "simple", "search_analyzer": "simple", "payloads": false } } }}'3）添加文件：
curl -XPUT "http://localhost:9200/test_index/product/1" -d'{ "title": "Product1", "sales": "6", "rating": "0.0", "cost": "45.00", "tags": [ "blog", "magazine", "responsive", "two columns", "wordpress" ], "suggest": { "input": [ "blog", "magazine", "responsive", "two columns", "wordpress" ] }, "category": "wordpress", "description": "Product1 Description", "createDate": "2013-12-19"}'curl -XPUT "http://localhost:9200/test_index/product/2" -d'{ "title": "Product2", "sales": "6", "rating": "0.0", "cost": "45.00", "tags": [ "blog", "paypal", "responsive", "skrill", "wordland" ], "suggest": { "input": [ "blog", "paypal", "responsive", "skrill", "wordland" ] }, "category": "wordpress", "description": "Product1 Description", "createDate": "2013-12-19"}'4）然后使用_suggest端点进行查询：
curl -XPOST "http://localhost:9200/test_index/_suggest" -d'{ "product_suggest":{ "text":"word", "completion": { "field" : "suggest" } }}'您将获得预期的结果：
{ "_shards": { "total": 2, "successful": 2, "failed": 0 }, "product_suggest": [ { "text": "word", "offset": 0, "length": 4, "options": [ { "text": "wordland", "score": 1 }, { "text": "wordpress", "score": 1 } ] } ]}当然，可以稍微改进此解决方案，特别是通过修剪一些重复的数据，但这应该为您指明正确的方向。
