By default, it seems that all my strings are dynamically mapped to a multifield like below. I am concerned with mapping explosion
Does those multi fields are counted as 2 fields? here below, REG
and REG.keyword
are considered as 1 field, or 2 fields?
If it is 2 fields, how can I change the dynamic mapping to map json strings into only keywords?
"REG" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
}
