In my index I have data that resembles
"field_1" : "here I am"
"Display_name" : null
"field_1":"I am also here"
"Display_name" : "test"
I am trying to remove the display_name field and value from Doc1.
I would like a query to remove the fields that are Null from the index. I do not want to have to reindex all the data. I am currently using elastic 2.2
any help would be much appreciated.
