Hi,

We'we been using the following analyzer setup for ages:

"analysis": {  
"char\_filter": {  
"danish\_char\_mapping": {

},  
"danish\_synonyms\_pre\_token": {

"type": "word\_delimiter",  
"type\_table": [  
"_ =\> ALPHANUM"  
],  
"split\_on\_numerics": false  
}  
}  
}

And it has worked under the 1.x series, 2.x series and 5.x series. But now when I try to build a new index under ES 6.2.2, specifying the above analyzer setup in the settings section, I receive the following error, which I don't understand:

{  
"error": {  
"caused\_by": {  
"caused\_by": {  
"reason": "term: i/s analyzed to a token (i7s) with position increment != 1 (got: 0)",  
"type": "illegal\_argument\_exception"  
},  
"reason": "Invalid synonym rule at line 35",  
"type": "parse\_exception"  
},  
"reason": "failed to build synonyms",  
"root\_cause": [  
{  
"reason": "failed to build synonyms",  
"type": "illegal\_argument\_exception"  
}  
],  
"type": "illegal\_argument\_exception"  
},  
"status": 400  
}

Hope somebody can enlighten me.

Regards,  
Michael
