I tried to combine multiple different fields (Stored Fields) into a JSON object

and added in to lucene document as single field

I get a better performance while reading the field from the index.

though constructing the JSON requires additional time, It still retrieve the data faster

What is the reason for this ?





I done update reading and indexing the data

while reading i convert them back to single fields

from JSON object
