问题
I have a Rails app with searchkick gem. My model has a nested JSON field. I try to make it searchable with word_start match. When I set in explicitly like:
class Post < ApplicationRecord
searchkick word_start: [:nested_data_field]
end
I does not work, and I get error:
{"type"=>"mapper_parsing_exception", "reason"=>"failed to parse [nested_data_field]", "caused_by"=>{"type"=>"illegal_state_exception", "reason"=>"Can't get text on a START_OBJECT at 1:401"}} on item with id '2596'
How can I make this nested JSON field to match word_start?
I found the same issue here https://github.com/ankane/searchkick/issues/1149 - but it has no result.
回答1:
in this case, you have to explicitly define how fields should index in elasticsearch
class Post < ApplicationRecord
searchkick word_start: [:author_name, author_country]
def search_data # override indexing fields
{
tite: self.title,
date: self.created_at,
author_name: author[:name], # nested json(author field)
author_country: author[:country],
comments_ids: comments.map(&:id) # index as an array of ids
}
end
end
