Why is my very simple ElasticSearch query failing, SearchPhaseExecutionException

Question

Im trying to do a search for "dog chew" in the invention-title field in my PatentGrants type.
query url: POST http://localhost:9200/patents/patentGrants/_search
query body:

{
  "query": {
    "match_all": {
      "invention-title": "dog chew"
    }
  }
}

Below is a picture of the data in my patents index and below that is a picture of my query and the error message.

Answer 1

试试这个：

{
  "query": {
    "match": {
      "inventionTitle": "dog chew"
    }
  }
}

1. 屏幕截图中的字段名称为inventionTitle而不是invention-title。
2. https://www.elastic.co/guide/en/elasticsearch/reference/1.6/query-dsl-match-all-query.html - 使用match代替match_all。 match_all不接受搜索查询。
