Advance search with elasticsearch and rails - ruby-on-rails

Question

I want to use ElasticSearch to search with multiple parameters (name, sex, age at a time).
what I've done so far is included elastic search in my model and added a as_indexed_json method for indexing and included relationship.
require 'elasticsearch/model'
class User < ActiveRecord::Base
include Elasticsearch::Model
include Elasticsearch::Model::Callbacks
belongs_to :product
belongs_to :item
validates :product_id, :item_id, :weight, presence: true
validates :product_id, uniqueness: {scope: [:item_id] }
def as_indexed_json(options = {})
self.as_json({
only: [:id],
include: {
product: { only: [:name, :price] },
item: { only: :name },
}
})
end
def self.search(query)
# i'm sure this method is wrong I just don't know how to call them from their respective id's
__elasticsearch__.search(
query: {
filtered: {
filter: {
bool: {
must: [
{
match: {
"product.name" => query
}
}
],
must: [
{
match: {
"item.name" => query
}
}
]
}
}
}
}
)
end
end
User.import force: true
And In controller
def index
#category = Category.find(params[:category_id])
if params[:search].present? and params[:product_name].present?
#users = User.search(params[:product_name]).records
end
if params[:search].present? and params[:product_price].present?
#users = User.search(params[:product_price]).records
end
if params[:search].present? and params[:item].present?
if #users.present?
#users.search(item: params[:item], product: params[:product_name]).records
else
#users = User.search(params[:item]).records
end
end
end
There are basically 3 inputs for searching with product name , product price and item name, This is what i'm trying to do like if in search field only product name is present then
#users = User.search(params[:product_name]).records
this will give me records but If user inputs another filter say product price or item name in another search bar then it's not working. any ideas or where I'm doing wrong :/ stucked from last 3 days
