ElasticSerch match query result is empty - elasticsearch

Question

I have an index with documents that have 3 fields name, summary and tags
name is short text that contains small pharse e.g. "Japanese Handmade Sword"
summary is a long text that is description of certain products, it may be more then 200 words.
tags is an array of string with keywords, e.g. ["Japanese", "Antiquity", "Weapon", "Katana"]
I need to combine these fields into one search query to get desired search results. For example, when user searched "Japan" I should get this item. However, match query always gives me empty result, although I have data and can see all documents without query.
Here is my mapping and index settings that performs some tokenization for fields.
PUT lessons
{
"settings": {
"index": {
"number_of_shards": 1
},
"refresh_interval": "5s",
"similarity": {
"string_similarity": {
"type": "BM25"
}
},
"analysis": {
"analyzer": {
"autocomplete": {
"filter": [
"lowercase"
],
"tokenizer": "standard"
},
"autocomplete_search": {
"type": "custom",
"filter": "lowercase",
"tokenizer": "standard"
}
},
}
},
"mappings": {
"properties": {
"name": {
"type": "text",
"analyzer": "autocomplete",
"search_analyzer": "autocomplete_search",
"fielddata": true,
"fields": {
"keyword": {
"type": "keyword"
}
}
},
"summary": {
"type": "text",
"analyzer": "autocomplete",
"search_analyzer": "autocomplete_search",
"fielddata": true,
"fields": {
"keyword": {
"type": "keyword"
}
}
},
"tags": {
"type": "text",
"search_analyzer": "autocomplete_search",
"fielddata": true,
"fields": {
"keyword": {
"type": "keyword"
}
}
}
}
}
}
I am using Kibana and when run below query I get no result
GET lessons/_search
{
"query": {
"match": {
"summary": "Japan"
}
}
}
What is wrong with my index settings or mapping?

Answer 1

You can use a multi-match query, to search on multiple fields for the same query text
{
"query": {
"multi_match" : {
"query": "Japan",
"fields": [ "summary", "tags", "name" ]
}
}
}
