Failed to find minhash filter in kibana Dev app

[Fred12]

Hello,
after installing minhash filter in elasticsearch, I started kibana app and in the Dev tool, I copy&pasted the code to create the minhash filter mapping:
curl -XPUT 'localhost:9200/my_index' -d '{
"index":{
"analysis":{
"analyzer":{
"minhash_analyzer":{
"type":"custom",
"tokenizer":"standard",
"filter":["minhash"]
}
}
}
}
}'

But then, I got this error:

{
"error": {
"root_cause": [
{
"type": "illegal_argument_exception",
"reason": "Custom Analyzer [minhash_analyzer] failed to find filter under name [minhash]"
}
],
"type": "illegal_argument_exception",
"reason": "Custom Analyzer [minhash_analyzer] failed to find filter under name [minhash]"
},
"status": 400
}

I think the plugin installation is failed.

nope, the weirdo tutorial on this github page does not work, I used the code from this thread:
#15

and got it to work, I am just trying to figure out how I can do a search query, or a "more_like_this" query on the min_hash field.. it just doesn't work because its not text or term and I cannot convert it to text/ term.. how would I normally do it?
