ruby - two-way search with Hashes? -

i'm trying create database search programme using hash db storage.

i can search list using fellow member numbers how search using fragments of numbers (so entering 1 give 001, 010, 011, 021, etc...) or fragmented/full usernames (entering ni give nightc||ed , oni)

my current code follows:

#rdb nightc||ed, ©2015 db = hash.new() db["001"] = "oni" db["002"] = "eclipse" db["003"] = "saikou" db["004"] = "nightc||ed" db["005"] = "anime" db["006"] = "master" x = 0 num = db.count puts "in: member:" num.times |pair| puts "#{db.keys[x]} | #{db.values[x]}" x += 1 end puts "------------------- come in index number:" = gets.to_i -= 1 scheme "cls" puts "in: member: #{db.keys[i]} | #{db.values[i]}" sleep

first, iterate on hash. within each iteration, utilize include? search partial results in key and/or value.

here's way allow user come in either partial number or partial name:

db = hash.new() db["001"] = "oni" db["002"] = "eclipse" db["003"] = "saikou" db["004"] = "nightc||ed" db["005"] = "anime" db["006"] = "master" puts "enter search term" search_term = gets.chomp.downcase results = db.select |k,v| k.downcase.include?(search_term) || v.downcase.include?(search_term) end results.size.times |x| puts "#{results.keys[x]} | #{results.values[x]}" end

results:

enter search term 1 001 | oni come in search term ni 001 | oni 004 | nightc||ed 005 | anime
