Hi all,

I am really new to elasticsearch, and so far I simply couldn't create an  
index with DFR as the similarity metric. I haven't even found any useful  
example on that. Could you please help me out with this? Here's what I'm  
doing (after many different attempts):

curl -XPOST '[http://localhost:9200/tweeter/](http://localhost:9200/tweeter/)' -d '  
{  
"settings": {  
"index": {  
"similarity": {  
"default": {  
"index": {  
"type": "DFR"  
},  
"search": {  
"type": "DFR"  
}  
}  
}  
}  
}  
}'

Cheers and thanks in advance

It seems this thing here works, but I thinks it's verbose.

curl -XPOST '[http://localhost:9200/tweeter/](http://localhost:9200/tweeter/)' -d '  
{  
"settings" : {  
"index" : {  
"similarity" : {  
"esserverbook\_dfr\_similarity" : {  
"type" : "DFR",  
"basic\_model" : "g",  
"after\_effect" : "l",  
"normalization" : "h2",  
"normalization.h2.c" : "2.0"  
}  
}  
}  
}  
}'

I found it here:
