Tengo que buscar a mis amigos.

[waxapax]

English Translation

I have to look for my friends.

Shouldn’t it be buscarles a mis amigos?

buscarles a mis amigos

That doesn’t sound right to me; “mis amigos” is the direct object, so no object pronoun is required. Cf. “Tengo que dárselo a mis amigos.”
