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


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?




Those are pun-based catchphrases for the job search service by the name of
サーチ.

First of all, 「あれ」 is the _**imperative**_ form of 「ある/有る」; therefore, it is a
verb. In case someone is wondering, this 「あれ」 has no relation to the
「あれ」("that") as in 「これ/それ/ **あれ** /どれ」.

In fact, the two 「あれ's」 are even pronounced quite differently -- 「あれ{HL}」 for
the verb and 「あれ{LH}」 for the demonstrative pronoun.

> 「Noun + あれ」 means "Let there be [noun]!"

One of the nouns that are most often used in the expression above is 「幸{さち}」
("happiness"). So, for instance, 「君{きみ}に幸あれ！」 means " _ **Wish you
happiness!**_ ", " _ **Much happiness to you!**_ ", etc. To the newly weds, we
often say 「お二人{ふたり}に幸あれ」.

Now, 「サーチ」, as in searching on the internet, sounds sort of like 「幸{さち}」
except for the length of the first syllable, which makes this pun work. You
are turning the common phrase 「幸あれ」 into an advertisement catchphrase 「サーチあれ」
for the job search company.
