HSK5 - 'make / do / create' verbs (meaning of 搞 unknown)
搞 is an omnipotent verb used in oral language. It emerged very lately as gao3，with which the modern meanings associated has nothing to do with its ancient usage.

Basically, most important usage is to attach it to any abstract noun/verb, meaning conceptual "do":

搞艺术/搞创作/搞发展/搞卫生/搞活动/搞名堂/搞关系...

Even in oral language, 搞 has a tone of bureaucratese, because using (abusing) these kind of all-purpose verbs are a prominent feature of government officials' speech/writing.

Other than "do", 搞 can mean "get", but I would say it's more like "do something such that":

In 搞两张票来/搞到手, you may treat 搞 as "get", but this is not the essence.

Because it is 来/到手 that indicate "get": do something such that two tickets "come" （搞两张票来）＞"get"/ do something such that something to your hand（搞到手）＞"get"

So it can extend to: 搞好关系/搞砸事情/搞定/搞完/搞大肚子/搞死/搞出人命...

The last usage, though somehow overlaping, is "make":

搞事/搞钱/搞核武器...
