Suggester wills return fail results if suggest mode is missing.
I have example:
#analyzer
index:
analysis:
analyzer:
vi_analyzer:
type: custom
tokenizer: whitespace
filter: [trim, lowercase, hunspell_vi]
filter:
hunspell_vi:
type: hunspell
locale: vi_VN
delete the index
curl -XDELETE localhost:9200/test
insert a document
curl -XPUT localhost:9200/test/test/1 -d '{
"title": "bong bay"
}'
curl -XPUT localhost:9200/test/test/2 -d '{
"title": "ba bong bong"
}'
curl -XPUT localhost:9200/test/test/3 -d '{
"title": "ba bong bay"
}'
Suggest
curl -XPOST 'localhost:9200/_suggest' -d '{
"_suggestion" : {
"text" : "ba",
"term" : {
"field" : "title",
"suggest_mode": "missing",
"sort" : "score",
"min_word_length" : 1
}
}
}'
Results
{"_shards":{"total":52,"successful":52,"failed":0},"_suggestion":
[{"text":"ba","offset":0,"length":2,"options":[{"text":"bay","score":0.5,"freq":1}]}]}
