What does it mean to "store" a field?

Hi Jorg/Nik,

I tried the scenario like one with storing all fields and one without. So what i came across is

-- The size of index is reduced as mentioned in preceding posts as well
-- Search time for same query is slightly less with not storing the individual field
-- But here I am getting an issue like I am not able to retrieve the content with highlight if I am using store:No for fields. So how I can overcome this issue without storing the field.

Also its mentioned like : You can even highlight the content from _source forcefully by adding "force_source" : true as mentioned in below link. So any Idea how I can achieve that using not storing the fields.

You must store the field for highlighting.

Hi Jorg,

But while exploring the same I came across somethink like mentioned below:

You can even highlight the content from _source
forcefully by adding "force_source" : true as mentioned in below link. So
any Idea how I can achieve that using not storing the fields.
