Is edgegram_analyzer predefined analyzer?

In our project we have used "analyzer": "edgegram_analyzer" for one property in mapping template. But in elastic search website I can't see any reference for that analyzer. When I am searching it in goggle with 'edgegram_analyzer' it is giving results of 'edge ngram tokenizer'.

Does "edgegram_analyzer" exist? If yes, then is it a predefined analyzer like standard or others?

See below:

"properties": {
"name": {
"analyzer": "edgegram_analyzer",
"index": "analyzed",
"type": "text",
"fields": {
"raw": {
"analyzer": "lowercase_keyword",
"type": "text"

I think this is an analyzer you created within your index settings.



You are right. I just checked the templates and I saw it under index settings. So then it's a customized analyzer which we created.
