Implementing "search as you type" example

Elastic Stack Elasticsearch

Hi,

I'm trying to implement the "search as you type" example
from http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/_index_time_search_as_you_type.html

Can someone see what I'm doing wrong?

curl -XDELETE localhost:9200/my_index
echo
curl -XPUT localhost:9200/my_index -d '
{

"analysis": {
"filter": {
"autocomplete_filter": {
"type": "edge_ngram",
"min_gram": 1,
"max_gram": 20
}
},
"analyzer": {
"autocomplete": {
"type": "custom",
"tokenizer": "standard",
"filter": [
"lowercase",
"autocomplete_filter"
]
}
}
}
}
}'
echo
curl -XPUT localhost:9200/my_index/_mapping/my_type -d '
{
"my_type": {
"properties": {
"name": {
"type": "string",
"analyzer": "autocomplete"
}
}
}
}'
echo
curl localhost:9200/my_index/my_type/_bulk -d '

{ "name": "Brown foxes" }
{ "index": { "_id": 2 }}
{ "name": "Yellow furballs" }
'
echo
curl localhost:9200/my_index/my_type/_search -d '
{
"query": {
"match": {
"name": "brown fo"
}
}
}'
echo
curl localhost:9200/my_index/my_type/_validate/query?explain -d '
{

Sorry, I should also explain the problem :wink:

For both of the searches I'm getting the following:

{"took":1,"timed_out":false,"_shards":{"total":1,"successful":1,"failed":0},
"hits":{"total":0,"max_score":null,"hits":}}

For implementing good autocomplete I recommend you look at the completion
suggester - its much faster and has more capabilities. It was built
especially for that.

See Elasticsearch Platform — Find real-time answers at scale | Elastic and
Elasticsearch Platform — Find real-time answers at scale | Elastic

You can then complement it with Phrase Suggester to recommend spelling
corrections etc

edge-grams are less than ideal for this use case given the above tools

That's fine, but I still want to know what I'm doing wrong in my example
(taken pretty much verbatim from the link provided).

That said, I am planning on evaluating both for my use case. The problem I
have with the suggester is the duplication. That said, I'd rather not
debate that right now as I've not even really looked into it yet :wink:
