You're right, it works by changing the analyzer.
Now evolving issues, I customize the 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

Why the result with "mun" is not displayed ?
Thanks for your help
