弹性搜索没有找到

我已经装在elasticsearch一些数据，并验证了它的被索引的话：弹性搜索没有找到

curl -XGET http://localhost:9200/studies/gov/NCT02953782 
{"_index":"studies","_type":"gov","_id":"NCT02953782","_version":5,"found":true,"_source":{"status": "Recruiting", "is_fda_regulated": false, "description": "", "open_study_countries": ["United States"], "phase": "Phase 1/Phase 2", "completion_date": "2018-05-01", "references": [], "is_drug_intervention": true, "keywords": ["Colorectal Neoplasms, Hu5F9-G4, CD47, cetuximab"], "id": "NCT02953782", "title": "Trial of Hu5F9-G4 in Combination With Cetuximab in Patients With Solid Tumors and Advanced Colorectal Cancer", "summary": " This trial will evaluate Hu5F9-G4 in combination with cetuximab. Hu5F9-G4 is a monoclonal antibody which is designed to block a protein called CD47, which is widely expressed on human cancer cells. Blocking CD47 with Hu5F9-G4 may enable the body's immune system to find and destroy the cancer cells. Cetuximab is a monoclonal antibody drug that is used for treatment of certain types of colorectal cancer as well as head and neck cancer.\n The major aims of the study are: (Phase 1b) to define the safety profile and to determine a recommended Phase 2 dose for Hu5F9-G4 in combination with cetuximab, and (Phase 2) to evaluate the objective response rate of Hu5F9-G4 in combination with cetuximab in patients with advanced colorectal cancer.

，当我搜索，使用简单的查询搜索中的一个词，它没有找到它：

curl -XPOST http://localhost:9200/studies/_search?pretty=true -d '{ 
    "query": { 
    "simple_query_string" : { 
     "query": "Colorectal", 
     "analyzer": "snowball" 
    } 
    } 
}' 
{ 
    "took" : 1, 
    "timed_out" : false, 
    "_shards" : { 
    "total" : 5, 
    "successful" : 5, 
    "failed" : 0 
    }, 
    "hits" : { 
    "total" : 0, 
    "max_score" : null, 
    "hits" : [ ] 
    } 
}

有谁知道如何使它工作？

你用标准分析仪而不是雪球试过了吗？ –

呵呵，我把分析仪改成了“标准”，它工作正常。是否有关于分析仪的更多信息？ – max

我发布了一个答案，试图给分析仪添加一些参考 –

您的simple_query_string query与query_string query一样，是针对index.query.default_field索引设置执行的，默认值为_all。 _all字段默认使用Standard Analyzer进行分析。

您正在查询中使用的是Snowball Analyzer，这可能与您在索引时使用的不一致。

如果您确实不需要雪球分析仪，则可以询问您的查询以使用标准分析仪。相反，如果您确实想要使用雪球分析仪，则在开始索引文档之前，您应该在_all字段中输入mapping这样的字段，但请确保您没有打破任何其他查询。

这是你如何把雪球分析仪在映射为gov int类型的studies指数：

curl -XPUT http://localhost:9200/studies/_mapping/gov -d'{ 
    "_all": { 
    "analyzer": "snowball" 
    } 
}'

这之后你需要再次索引文档。
