Hi,

We have indexed 10k documents which have very large text field. The text field of a document is an union of the text in the element pages.  
The mapping looks like that

"docs":{  
"properties":{  
"text":{  
"type":"string",  
"index":"analyzed",  
"term\_vector":"yes",  
"index\_options":"offsets"  
}

It takes 4s when searching with text field in the query:  
{  
"fuzzy\_like\_this\_field":{  
"text" : {  
"like\_text" : query,  
"max\_query\_terms" : 12  
}  
}  
}

And it takes less than 1 s when searching without text field in the query.

Could you help in optimising the queries against the very large text field in this case.

Thanks a lot
