Hi all,
I have indexed a field as both double and keyword. Searching is working fine but i have issues with highlighting. As i see, highlighting is not happening over datatypes other than text fields.
My mapping file is:
{
"sorting": {
"mappings": {
"_doc": {
"properties": {
"VALUE": {
"type": "double",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
}
}
}
}
}
My search query is
{
"query": {
"bool": {"should": [
{
"query_string": {
"query":"\"230\"",
"fields":[],
"boost":"50"
}
}, {
"multi_match": {
"query":"230",
"type":"phrase",
"boost":"10",
"slop":"2",
"fields":[]
}},{
"multi_match": {
"query":"230",
"fields":[]
}}
]
}
}, "highlight": {
"type" : "unified",
"fields": {
"*": {}
}
}
}
and the results are
"hits": [
{
"_index": "sorting",
"_type": "_doc",
"_id": "2",
"_score": 61,
"_source": {
"VALUE": "230"
},
"highlight": {
"VALUE.keyword": [
"<em>230</em>"
]
}
},
{
"_index": "sorting",
"_type": "_doc",
"_id": "1",
"_score": 61,
"_source": {
"VALUE": 230
},
"highlight": {
"VALUE.keyword": [
"<em>230</em>"
]
}
}
]
Why is highlight not happening over Value and happening over value.keyword.
I wish to know why highlighting is not happening ovr fields of data type integer, double etc.
