different analyzers in different fields - elasticsearch

Question

Because in my mapping below, when I put the URL field with the analyzer different from the title and description fields when I do a search simultaneously in the three fields, it doesn't return anything even if I have one of the three words below in each field
{
"settings": {
"index": {
"number_of_shards": "5",
"number_of_replicas": "0",
"analysis": {
"filter": {
"stemmer_plural_portugues": {
"name": "minimal_portuguese",
"stopwords" : ["http", "https", "ftp", "www"],
"type": "stemmer"
},
"synonym_filter": {
"type": "synonym",
"lenient": true,
"synonyms_path": "analysis/synonym.txt",
"updateable" : true
},
"shingle_filter": {
"type": "shingle",
"min_shingle_size": 2,
"max_shingle_size": 3
}
},
"analyzer": {
"analyzer_customizado": {
"filter": [
"lowercase",
"stemmer_plural_portugues",
"asciifolding",
"synonym_filter",
"shingle_filter" ],
"tokenizer": "standard"
},
"analyzer_url": {
"filter": [
"lowercase",
"stemmer_plural_portugues",
"asciifolding" ],
"tokenizer": "lowercase"
}
}
}
}
},
"mappings": {
"properties": {
"id": {
"type": "long"
},
"data": {
"type": "date"
},
"quebrado": {
"type": "byte"
},
"pgrk": {
"type": "integer"
},
"url_length": {
"type": "integer"
},
"title": {
"analyzer": "analyzer_customizado",
"type": "text",
"fields": {
"keyword": {
"ignore_above": 256,
"type": "keyword"
}
}
},
"description": {
"analyzer": "analyzer_customizado",
"type": "text",
"fields": {
"keyword": {
"ignore_above": 256,
"type": "keyword"
}
}
},
"url": {
"analyzer": "analyzer_url",
"type": "text",
"fields": {
"keyword": {
"ignore_above": 256,
"type": "keyword"
}
}
}
}
}
}
in the query below the three words exist each of the fields, but it only returns results if I search for words that are in the title and in the description, if I also search for the word that is in the URL field that has the different analyzer does not return anything.
if I search only the words that are in the title and description field you will normally find, if I search only the word that is in the URL field also finds it, however if I search for the three words that exist in the three fields it doesn't return anything.
{
"from": 0,
"size": 10,
"query": {
"multi_match": {
"query": "carro moto aviao",
"type": "cross_fields",
"fields": [
"title",
"description",
"url"
],
"operator": "and"
}
}
}

Answer 1

The issue is that you are using the operator as and which means all three words carro moto aviao must present, can you change it to OR and see if its returns result.
Adding a working example with you mapping, sample data and with search query with or parameter and confirming that it works.
Sample doc
{
"title": "carro",
"description": "moto",
"url": "aviao"
}
Search query with OR param
{
"from": 0,
"size": 10,
"query": {
"multi_match": {
"query": "carro moto aviao",
"type": "cross_fields",
"fields": [
"title",
"description",
"url"
],
"operator": "or"
}
}
}
Search result
"hits": [
{
"_index": "jean",
"_type": "_doc",
"_id": "1",
"_score": 0.5753642,
"_source": {
"title": "carro",
"description": "moto",
"url": "aviao"
}
}
]
Note: confirmed that it doesn't work with and param if your query.
