Hi There  
using ES 5.5  
this is the section in my template  
"analysis": {  
"filter": {  
"synonym": {  
"type": "synonym",  
"synonyms\_path": "analysis/synonym.txt",  
"tokenizer": "lowercase"  
}  
},  
"analyzer": {  
"ngraman": {  
"filter": [  
"lowercase",  
"synonym"  
],  
"type": "custom",  
"tokenizer": "ngram\_tokenizer"  
},  
"search\_standard": {  
"filter": [  
"lowercase",  
"synonym"  
],  
"type": "custom",  
"tokenizer": "search\_tokenizer"  
}  
},  
"tokenizer": {  
"ngram\_tokenizer": {  
"token\_chars": [  
"letter",  
"digit",  
"punctuation"  
],  
"min\_gram": "3",  
"type": "edge\_ngram",  
"max\_gram": "17"  
},  
"search\_tokenizer": {  
"token\_chars": [  
"letter",  
"digit",  
"punctuation"  
],  
"type": "whitespace"  
}  
}  
}

this is my synonyms file:

tech =\> technology  
resistor =\> resistore  
capacitor =\> capacitore , capecitore  
capacitor =\> TEST  
TI =\> Texas instrume  
a2c =\> adc

all of the synonyms work besides this one:  
a2c =\> adc

is there a reason ? digits dont work?
