You're right, it works by changing the analyzer.
Now evolving issues, I customize the analyzer
PUT hotels
{
"settings": {
"analysis": {
"analyzer": {
"labelstreet_analyzer": {
"type": "custom",
"tokenizer": "nGram_tokenizer",
"filter": [
"lowercase",
"elision",
"stopwords"
]
}},
"tokenizer": {
"nGram_tokenizer": {
"type": "nGram",
"min_gram": "2",
"max_gram": "4",
"token_chars": [
"letter",
"digit"
]
}
},
"filter": {
"elision": {
"type": "elision",
"article": [
"l",
"m",
"t",
"qu",
"n",
"s",
"j",
"d"
]
},
"stopwords": {
"type": "stop",
"stopwords": [
"_french_"
],
"ignore_case": true
}
}
}
},
"mappings": {
"hotel": {
"properties": {
"name": {
"type": "string",
"analyzer": "labelstreet_analyzer"
},
"city": {
"type": "string",
"analyzer": "labelstreet_analyzer"
},
"name_suggest": {
"type": "completion",
"analyzer": "labelstreet_analyzer"
}
}
}
}
}
PUT /hotels/hotel/1
{
"name": "Mercure Hotel Munich",
"city": "Munich",
"name_suggest": {
"input": [
"Mercure Hotel Munich",
"Mercure Munich"
]
}
}
PUT hotels/hotel/2
{
"name": "Hotel Monaco",
"city": "Munich",
"name_suggest": {
"input": [
"Monaco Munich",
"Hotel Monaco"
]
}
}
PUT /hotels/hotel/3
{
"name": "Courtyard by Marriot Munich City",
"city": "Munich",
"name_suggest": {
"input": [
"Courtyard by Marriot Munich City",
"Marriot Munich City"
]
}
}
If i check the analyser, I get the result I want. That is, if I type "mun",
the tokenizer gets me a right token
GET /hotels/_analyze?analyzer=labelstreet_analyzer&text=Munich
Yet when I execute this query, the result is null
POST /hotels/_suggest
{
"hotels" : {
"text" : "mun",
"completion" : {
"field" : "name_suggest"
}
}
}
Why the result with "mun" is not displayed ?
Thanks for your help

Completion fields use the simple analyzer by default, which removes
numbers. If you try another analyzer that keeps numbers such as the
standard analyzer, this should work:
PUT /hotels
{
"mappings": {
"hotel" : {
"properties" : {
"name" : { "type" : "string" },
"city" : { "type" : "string" },
"name_suggest" : {
"type" : "completion",
"analyzer": "standard"
}
}
}
}
}

Mapping is very basic. There are no analyzers.

You are probably using an analyzer that removes numbers?

Hi all,
I try to put an auto completion system based on ES.
This article Elasticsearch Platform — Find real-time answers at scale | Elastic helps
me a lot, but I don't understand a case:
PUT /hotels
{
"mappings": {
"hotel" : {
"properties" : {
"name_suggest" : {
"type" : "completion"
}
}
}
}
}
PUT /hotels/hotel/1
{
"name_suggest" : {
"input" : [
"21 Mercure Hotel Munich",
"24 Mercure Munich"
]
}
}
PUT hotels/hotel/2
{
"name_suggest" : {
"input" : [
"Monaco Munich",
"Hotel Monaco"
]
}
}
When i post :
POST /hotels/_suggest
{
"hotels" : {
"text" : "m",
"completion" : {
"field" : "name_suggest"
}
}
}
The result is 3 hotels : "21 Mercure Hotel Munich","24 Mercure
Munich", "Monaco Munich".
But when i post this request:
POST /hotels/_suggest
{
"hotels" : {
"text" : "2",
"completion" : {
"field" : "name_suggest"
}
}
}
There is no result ...
Any Idea ?
