}
i'm getting following output which is not correct
Finalresult:{contains=456, document<indexed,tokenized<contents:this=456, information=456, is=139, it=140, java=912, prg=456, related=456}
i should get the following output
information=1,java=2, prg=1, related=1
can u please suggest me to get the required output. thanks
