A search filter to an array of objects in Ruby

app.rb

# Sample array of user objects
users = [
  { id: 1, first_name: "John", last_name: "Doe", age: 30, email: "[email protected]" },
  { id: 2, first_name: "Jane", last_name: "Smith", age: 25, email: "[email protected]" },
  { id: 3, first_name: "Michael", last_name: "Johnson", age: 35, email: "[email protected]" },
  { id: 4, first_name: "Emily", last_name: "Brown", age: 28, email: "[email protected]" }
]

# Function to apply the search filter
def search_users(query, users)
  if query.nil? || query.strip.empty?
    # If the search query is empty, return the original array
    return users
  end

  search_query = query.strip.downcase

  # Filter the array and return only the objects that match the search query
  filtered_users = users.select do |user|
    # Iterate through all the keys (e.g., first_name, last_name, email, etc.)
    # and check if any of the values contain the search query
    user.values.any? do |value|
      value.to_s.downcase.include?(search_query)
    end
  end

  filtered_users
end

# Test the search_users function with a search query
search_query = "" # You can search using any keyword
result = search_users(search_query, users)

puts result
