Which way is better to accomplish query_string field search in multiple
fields with different weights?
1st way:
{
"query": {
"query_string": {
"query": "cats",
"fields": [
"en_keywords_1^5",
"en_keywords_2^2",
"en_keywords_3"
],
"use_dis_max": true
}
}
}
2nd way:
{
"query": {
"bool": {
"must": [
{
"query_string": {
"query": "cats",
"fields": [
"en_keywords_1",
"en_keywords_2",
"en_keywords_3"
]
}
}
],
"should": [
{
"query_string": {
"query": "cats",
"fields": [
"en_keywords_1"
],
"boost": 5
}
},
{
"query_string": {
"query": "cats",
"fields": [
"en_keywords_2"
],
"boost": 3
}
}
]
}
}
}
and What are pros and cons of both approaches?
