Can anyone enlightens me about below shortcut structure in Kotlin:

fun letsSearch(search: SearchModel.() -> SearchModel) {
//how to utilize search param here..

}

Perhaps the information about type safe builders can enlighten you https://kotlinlang.org/docs/type-safe-builders.html#how-it-works

SearchModel is passed into the lambda as ‘this’ and lambda expects it will return a SearchModel instance, so this basically looks like a function to update SearchModel, probably via copy

[Maciej Pigulski]

Link from Jan explains it on an example

Those are function literals with receiver https://kotlinlang.org/docs/lambdas.html#function-literals-with-receiver
