Hi,  
I'm trying to run next query on the index:  
"match": {  
"folders": {  
"query": "aqmkagm5mdizodk0ltg2ngbjltqxn2etotnmmc0wywy4m2vkmtg1mwealgaaaxfts4itp+bbtfaokkhwqimbaj1rfnbjd7voqhuq+f8apdiaaaibcqaaaa==",  
"type": "phrase\_prefix",  
"operator": "OR",  
"slop": 3,  
"max\_expansions": 20  
}  
}

and it's returns nothing, but when I run this query :  
"match": {  
"folders": {  
"query": "aqmkagm5mdizodk0ltg2ngbjltqxn2etotnmmc0wywy4m2vkmtg1mwealgaaaxfts4itp+bbtfaokkhwqimbaj1rfnbjd7voqhuq+f8apdiaaaibcqaaaa=="  
}  
}

it's return results.  
Am I missing something ? But, as far as I understand phrase\_prefix should return in this case as well ?

Thanks
