Elasticsearch 通用搜索查询

Question

I have a string "Jhon Abraham 18". I want to create search query that will search by divided by spaces words from the string in an index. This search have to be set to all fields of the index and you don't know what meaning have to be mapped(set) to a field. So, I have a document:

{
  "_index": "recipient",
  "_type": "recipient",
  "_id": "37a15258d9",
  "_version": 1,
  "_score": 1,
  "_source": {
    "name": "Jhon ",
    "surname": "Abraham",
    "age": "18 ",
}

and I don't know to what fields of index meanings Jhon, Abraham and 18 correspond. I just have a string and by this string I want to search in all fields of the index documents. I can divide it by separete words by spaces but I don't know exact mapping fields for search. Also, I want to do it at Java. I'll be appreciate for help.

Answer 1

I think you should use query_string in elasticsearch.

https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html

This will solve your problem.

Answer 2

You can use multi match query, writing all fields or wildcards.
