Hi,  
I have a custom plugin that generates a list of struct objects. something like [{field 1: value,field 2: value},{field 1: value,field 2: value},,,,] for request field.

I updated the elasticsearch template and set type: nested for my plugin event mapping. How do i assign these values to the fields in go. using Mapstr.

indexing didnt help for event fields.

You have some sample code? Just assigning your struct might work (given symbols are exported). Otherwise you have to transform your structs into MapStr yourself.
