Scanario:
Suppose I have index with type 'names'
type names has only single field of type string in the from "first_name
last_name"
Now I want to search 'names' type to get suggestions when user typed
something in the input, user could type not whole word and user could type
some word with mistyping (and not wole word)
So I know how to get right result when user type part of the name
(correctly) "{part_of_the_name}*" or when he types whole word with the
mistyping "{whole_name_with_some_error}~0.7" But not both.
For example
types : names
val
mikkey mouse
hommer simpson
max pain
User type - [ma], he should get [mikkey mouse, max pain]
User type - [mix], he should get [max pain]
So I decided to use ngram analizer
{
"settings": {
"analysis": {
"filter": {
"name_ngrams": {
"side": "front",
"max_gram": 20,
"min_gram": 2,
"type": "edgeNGram"
}
},
"analyzer": {
"partial_name": {
"filter": [
"standard",
"lowercase",
"asciifolding",
"name_ngrams"
],
"type": "custom",
"tokenizer": "standard"
}
}
}
}
}
and mapping
{
"names": {
"properties": {
"val": {
"type": "string",
"analyzer": "partial_name"
}
}
}
}
But still can't get desired results.
Can somebody help?
Thanks.
