I am trying to add autocomplete to my search index.
I am struggling to trying to get the syntax correct.
I have search and found solutions to similar solutions but still can't seem
to get my syntax to work.
Please tell me what is wrong....
PUT /my\_index
{
"settings": {
"analysis": {
"filter": {
"autocomplete\_filter": {
"type": "edgeNGram",
"min\_gram": 2,
"max\_gram": 20,
"token\_chars": [
"letter",
"digit"
]
}
},
"analyzer": {
"my\_standard\_analyzer": {
"type": "standard",
"stopwords": []
},
"autocomplete": {
"title": {
"type": "custom",
"tokenizer": "standard",
"filter": [
"lowercase",
"autocomplete\_filter"
]
}
}
}
}
},
"mappings": {
"title": {
"properties": {
"title": {
"type": "multi\_field",
"fields": {
"title": {
"type": "string",
"analyzer": "title"
},
"autocomplete": {
"type": "string",
"index\_analyzer": "autocomplete",
"search\_analyzer": "title"
}
}
}
}
}
}
}

I am going to answer my own question and hope it helps someone else, below
is how I fixed it.
A few things were wrong, but I was also using the wrong names of my
analyzers in my mappings...
PUT /de\_assets\_index
{
"settings":{
"analysis":{
"filter":{
"autocomplete\_filter":{
"type":"edge\_ngram",
"min\_gram":1,
"max\_gram":20,
"token\_chars": [
"letter",
"digit"
]
}
},
"analyzer":{
"autocomplete":{
"type":"custom",
"tokenizer":"standard",
"filter":[
"lowercase",
"autocomplete\_filter"
]
},
"my\_standard\_analyzer": {
"type": "standard",
"stopwords":
}
}
}
},
"mappings": {
"title": {
"properties": {
"title": {
"type": "multi\_field",
"fields": {
"title": {
"type": "string",
"analyzer": "my\_standard\_analyzer"
},
"autocomplete": {
"type": "string",
"index\_analyzer": "autocomplete",
"search\_analyzer": "my\_standard\_analyzer"
}
}
}
}
}
}
}
