Hi
I am using elastic 5.1.1 in my environment . currently i am using the completion suggester on filed name post_hashtags . i am getting response as below for prefx "inv"
eg:
Req:
POST hashtag/_search?pretty&&filter_path=suggest.hash-suggest.options.text,suggest.hash-suggest.options._source
{"_source":["post_hashtags" ],
"suggest": {
"hash-suggest" : {
"prefix" : "inv",
"completion" : {
"field" : "post_hashtags"
}
}
}
Response :
{
"suggest": {
"hash-suggest": [
{
"options": [
{
"text": "invalid",
"_source": {
"post_hashtags": [
"invalid"
]
}
},
{
"text": "invalid",
"_source": {
"post_hashtags": [
"invalid",
"coment_me",
"daya"
]
}
}
]
}
]
}
}
Here "invalid" is returned twice because it is also a input string for same field "post_hashtags" in other document .
Problems is if same "invalid" input string present in 1000 documents in same index . i will get 1000 duplicated
suggestions
Can i apply aggregation kind of work on the field of type completion ?
Is there any way i can get unique suggestion instead of duplicated text field , even though if i have same input string given to a particular field in multiple documents of same index ?
