Hello guys,

I was trying to play with the suggest feature and get a headache when my  
first basic example was working but my complexe one wasn't giving results  
at all.  
I just figured out that when you have a source field at the higher level of  
your mapping/document, the suggest feature doesn't return anything.

Here is my mapping which the suggest feature doesn't work :

{  
"source" : {  
"properties" : {  
"domain" : {  
"type" : "completion",  
"analyzer" : "autocomplete",  
"payloads" : true,  
"preserve\_separators" : false,  
"preserve\_position\_increments" : false,  
"max\_input\_len" : 50  
},  
"forum" : {  
"type" : "completion",  
"analyzer" : "autocomplete",  
"payloads" : true,  
"preserve\_separators" : false,  
"preserve\_position\_increments" : false,  
"max\_input\_len" : 50  
},  
"source" : {  
"properties" : {  
"name" : {  
"type" : "completion",  
"analyzer" : "autocomplete",  
"payloads" : true,  
"preserve\_separators" : false,  
"preserve\_position\_increments" : false,  
"max\_input\_len" : 50  
}  
}  
}  
}  
}  
}

Here is my new working one. I just replaced source by toto.

{  
"source" : {  
"properties" : {  
"domain" : {  
"type" : "completion",  
"analyzer" : "autocomplete",  
"payloads" : true,  
"preserve\_separators" : false,  
"preserve\_position\_increments" : false,  
"max\_input\_len" : 50  
},  
"forum" : {  
"type" : "completion",  
"analyzer" : "autocomplete",  
"payloads" : true,  
"preserve\_separators" : false,  
"preserve\_position\_increments" : false,  
"max\_input\_len" : 50  
},  
"toto" : {  
"properties" : {  
"name" : {  
"type" : "completion",  
"analyzer" : "autocomplete",  
"payloads" : true,  
"preserve\_separators" : false,  
"preserve\_position\_increments" : false,  
"max\_input\_len" : 50  
}  
}  
}  
}  
}  
}

I've just created a new issue here

Thanks
