Hi ,

I have the following entry in my synonym properties

YU,Yeshiva University,Yale University

my college name field has the following mapping

"autocomplete\_search":{  
"type":"custom",  
"tokenizer":"whitespace",  
"filter":[  
"lowercase",  
"syns\_filter"  
]  
},  
"autocomplete\_index":{  
"type":"custom",  
"tokenizer":"whitespace",  
"filter":[  
"lowercase",  
"syns\_filter",  
"my\_edgeNgram"  
]  
}

When i query

{  
"fields": [  
"name"  
],  
"query": {  
"match": {  
"name": {  
"query": "YU"  
}  
}  
}  
}

my results are as below:

"name": "Yuba College"  
"name": "Yukon Beauty College"  
"name": "Yale University"  
"name": "Cambridge Junior College - Yuba City"

Tough "Yale University" matched completely from synonums still the other  
two results are higher up which matched "YU" why?
