Hi,
I've a quite common situation: I've an index for products with a barcode field:
"barcode": {
"type": "text",
"fields": {
"ngram": {
"type": "text",
"analyzer": "ngram",
"search_analyzer": "standard"
},
"keyword": {
"type": "keyword"
}
}
},
I need to get the MAX value for the barcode when it's a number: in fact in my index I could have either string values (ie. "MYBARCODE001245") or numeric values (i.e. "1234567890123"). I need to get the MAX value of numeric values.
In that even possible? I guess I need to change a little bit my schema index because I see the query can't run on my field like it is.
Thanks for your hints.
