 Hi Guys,

               I am having doubt if the filters by default use the 

```

analyzers and if they use, then which one and if i need to change it, how  
to change the analyzer of the filter.

Actually I have a query as follows:

{  
"query": {  
"filtered": {  
"query": {  
"bool": {  
"should": [  
[  
{  
"text": {  
"searchable.title": {  
"type": "phrase\_prefix",  
"query": "ys: bay",  
"analyzer": "simple"  
}  
}  
}  
]  
]  
}  
},  
"filter": {  
"or": [  
{  
"prefix": {  
"searchable.title": "ys: bay"  
}  
}  
]  
}  
}  
}  
}

It is not giving results, but if i use the following query, it giving the  
result:

{  
"query": {  
"filtered": {  
"query": {  
"bool": {  
"should": [  
[  
{  
"text": {  
"searchable.title": {  
"type": "phrase\_prefix",  
"query": "ys: bay",  
"analyzer": "simple"  
}  
}  
}  
]  
]  
}  
},  
"filter": {  
"or": [  
{  
"prefix": {  
"searchable.title": "ys"  
}  
}  
]  
}  
}  
}  
}

I think the \*":" \*is the reason, but i did not get any documentation  
regarding the filters and analyzers together. So can you give me the way??

Filters don't use analyzers at all.

Hard to tell without understanding the data you index, and the analyzer used for each one, but maybe the title is analyzed?
