What is the meaning of putting あれ at the end of these statements?

Question

I saw an ad for Indeed today that had a couple tag lines with an あれ at the end, and I don't understand their use: 求人募集【きゅうじんぼしゅう】にサーチあれ。 仕事【しごと】、バイトさがしにサーチあれ。 Normally I'd assume that あれ would be something like して, since サーチ is a n-する verb, but that's obviously not the case here. I know あれ has several meanings, but usually it just means "that". Are these sentences saying "That with which jobs are searched," or is this a separate meaning or colloquialism I'm not familiar with?

Answer 1

As other's expert answer, ''サーチあれ'' is hanged two words, ''サーチsearch'' and ''さちhappiness''.

If I add grammar explanation, ’’あれ’’　is archaic word ''あり''verb (=there is) ,imperative form.

Answer 2

サーチあれ is their ad language they came up with; however, we use "幸あれ/さちあれ" which means "May it bring you happiness/May you find happiness." The advertiser may have played on wordsー "サーチあれ” for "さちあれ/幸あれ" to make the ad mean that if you use Indeed for job search, you'll be able to find/get what you're looking for, and you'll be happy.
