Hi,

I inserted some data of two records into an index say first record contains a field 'Hello World' and second record contains a field 'hello WorLD'. I want to query to match exact word with case insensitive so that i can get two records as my result.

Can some one please help on this.

Thanks  
Raj

Look into analysis, by default ES will lower case everything as it indexes things.

Thank you . But if i already have inserted data which is case sensitive ( as I can't compromise on my data ). How can i query case sensitive data which matches exact word with different cases.  
For example : if i query for 'hello world'  
it can return : 'Hello WOrld', 'hello world', 'HELLO world'

Is there any pointers on this please ..

See my previous response, ES normalises things for both indexed data and searches, so this is the default behaviour.
