Search method Ruby - ruby-on-rails

Question

I made this method for a search method in ruby with a form.
I think, that this code can be simplify. What do u think ?
And I have an issue. When a user does not enter anything in the form, the results display all the tips in the database.
But when a user combines two searches, for example a keywords and a country, the result is all the tips that have the keywords as well as all the tips that have the country concerned. Except what I'm looking for is for the two criteria to be combined.
Search.rb
require 'pry'
class Search < ApplicationRecord
def self.search(keywords, category_id,city,country)
table_of_ids_country = []
table_of_ids_city = []
table_of_ids_title = []
table_of_ids_cats = []
two_searches_ids = []
merged_table_of_tips_ids = []
#results = []
tips_by_country = Tip.where(["country like?",country]) if country.present?
tips_by_city = Tip.where(["city like?",city]) if city.present?
tips_by_keyword = Tip.where(["title LIKE?","%#{keywords}%"]) if keywords.present?
tips_by_cat = Category.where(["id = :id",{id:category_id}]) if category_id.present?
two_searches = Tip.where(["title LIKE?",keywords]) if keywords.present? && Category.where(["id = :id",{id:category_id}]) if category_id.present?
if tips_by_country != nil
tips_by_country.each do |tip|
tip.id
table_of_ids_country << tip.id
end
end
if tips_by_city != nil
tips_by_city.each do |tip|
tip.id
table_of_ids_city << tip.id
end
end
if tips_by_keyword != nil
tips_by_keyword.each do |tip|
tip.id
table_of_ids_title << tip.id
end
end
if two_searches != nil
two_searches.each do |tip|
tip.id
two_searches_ids << tip.id
end
end
if tips_by_cat != nil
Category.find(tips_by_cat[0].id).tips.each do |tip|
table_of_ids_cats << tip.id
end
end
merged_table_of_tips_ids = [table_of_ids_title, table_of_ids_cats,table_of_ids_city,table_of_ids_country,two_searches_ids].flatten
merged_table_of_uniq_tips_ids = merged_table_of_tips_ids.uniq
merged_table_of_uniq_tips_ids.each do |tip|
result = Tip.find(tip)
#results << result
binding.pry
end
return #results
end
end
searches_controller
require 'pry'
class SearchesController < ApplicationController
def new
#search = Search.new
end
def create
#search = Search.create(search_params)
redirect_to #search
end
def show
#search = Search.find(params[:id])
#search = Search.search(#search.keywords, #search.category_id,#search.city,#search.country)
#Permet d'envoyer les paramètres au model search et à les réutilisé dans la méthode self.search
end
private
def search_params
params.require(:search).permit(:keywords,:category_id,:id,:city,:country)
end
end
my form :
<%=form_for #search do |f| %>
<div class="form-group">
<%= f.label :keywords, "Mots-clés" %>
<%= f.text_field :keywords, class: "form-control", placeholder: "plongée, randonnée, temple..." %>
</div>
<div class="form-group">
<%= f.label :city, "Mots-clés" %>
<%= f.text_field :city, class: "form-control", placeholder: "plongée, randonnée, temple..." %>
</div>
<div class="form-group">
<%= f.label :country, "Mots-clés" %>
<%= f.text_field :country, class: "form-control", placeholder: "plongée, randonnée, temple..." %>
</div>
<div class="form-group">
<%= f.label :category_id, "Catégories" %><br>
<%= f.collection_select :category_id, Category.all, :id, :name, :include_blank => true %>
</div>
<div class="form-group d-flex justify-content-center">
<%= f.submit "Rechercher", class: "btn btn-primary" %>
</div>

class Search < ApplicationRecord
def self.search(keywords, category_id,city,country)
ids = if keywords.present? && category_id.present?
Tip.keywords(keywords).pluck(:id) & Category.category_id(category_id).pluck(:id)
elsif [keywords, category_id, city, country].any?(&:present?)
Tip.country(country)
.city(city)
.keywords(keywords)
.pluck(:id)
else
[]
end
Tip.find(ids.uniq)
end
end
class Category < ApplicationRecofd
scope :category_id, ->(category_id) {
where(["id = :id",{id:category_id}])
}
end
class Tip < ApplicationRecord
scope :country, ->(country) {
where("country like?",country) if country.present?
}
scope :city, ->(city) {
where("city like?",city) if city.present?
}
scope :keyword, ->(keywords) {
tips = tips.where("title LIKE?","%#{keywords}%") if keywords.present?
}
end
also notice I'm doing a union on category ids, so keep in mind
2.5.1 :002 > [1,2] && [2,3]
=> [2, 3]
2.5.1 :003 > [1,2] & [2,3]
=> [2]
