We would like to clarify regarding one of the functions of elastic search.
https://www.elastic.co/guide/en/elasticsearch/reference/6.2/query-dsl-query-string-query.html#_ranges
According to the documentation, by using square brackets, [ ] , you’re searching inclusively.
Our sample queries were “[49% TO 90%]” AND “[50% TO 90%]”.
But, when we ran the command, the record with 50% did not show on the first query.
By inserting the documents without specifying the datatype of the field_name field in the mapping. Elasticsearch will create 2 versions of the field (text and keyword).
If you analyze the field_name field with the value "50%", it's indexed as "50" (text type).
So that means, to get the expected result, you should run the query, with the keyword version :
GET testing_with_percent/_search
{
"query": {
"query_string": {
"query": "field_name.keyword: [50% TO 90%]"
}
}
}
or with the indexed values :
GET testing_with_percent/_search
{
"query": {
"query_string": {
"query": "field_name: [50 TO 90]"
}
}
