Scala Slick 编译查询等同于 "select * from table where word in (words)"

Question

我的问题是：如何创建等同于以下内容的 Slick 编译查询 SQL：

select * from table where word in ('word1', 'word2', 'word3')

我目前遇到的代码如下所示：

val findByWords = Compiled { words: Set[String] =>
  keywords.filter(_.word inSet words)
}

编译时出现如下错误：

Computation of type Set[String] => slick.lifted.Query[com.company.business.db.CensoredKeyWords,com.company.business.db.CensoredKeyWords#TableElementType,Seq] cannot be compiled (as type C)
val findByWords = Compiled { words: Set[String] =>
                           ^

注意箭头指向花括号。

我正在使用 Slick 3.2.1。斯卡拉 2.12.3

好像不能用inSet编译。
