How to send space in auto complete quires.

My Mapping and setting is as below

{  
"settings":{  
"index":{  
"analysis":{  
"analyzer":{  
"autocomplete":{  
"tokenizer":"engram",  
"filter":[  
"lowercase"  
]  
}  
},  
"tokenizer":{  
"engram":{  
"type":"edgeNGram",  
"min\_gram":3,  
"max\_gram":10  
}  
}  
}  
}  
},  
"mappings":{  
"collegeName":{  
"properties":{  
"title":{  
"type":"string",  
"index\_analyzer":"autocomplete",  
"index":"analyzed",  
"search\_analyzer":"standard"  
}  
}  
}  
}  
}

data in ES

{  
"title":"mandala tech"

}

{  
"title":"Mass Institute Technology"

}

{  
"title":"Massach Institute of tech"

}

When i query as q=title:"Mass" i get the below results which is fine

- "Massach Institute of tech"
- "Mass Institute Technology"

When i query as q=title:"Mass I" i still get the below results but it  
should be only one.

- "Massach Institute of tech"
- "Mass Institute Technology"

Regards  
Paul

Hi Paul,

first, this is a theorie, no valid answer 😉

I would guess it it down to the way you query the index. You use uri  
search, so look at Query String Query. Query String Query uses Query String  
syntax, and there in the docs is written: "The query string is parsed into  
a series of _terms_ and _operators_. A term can be a single word — quick or  
brown — or a phrase, surrounded by double quotes — "quick brown" — which  
searches for all the words in the phrase, in the same order."  
So, if I understand it right your query aint for one term "Mass I" but for  
two, "Mass" and "I". Still, I am not completely sure to what kind of query  
it is transformed and why you get a result at all. May be you could run it  
with explain option?
