我试图使用’OR’||在equalTo()方法中的语句,但这似乎不起作用.我是否必须为每个值单独调用,或者是否有办法在firebase中进行条件查询？

export const startSetContent = () => {
  return (dispatch,getState) => {
    const ref = database.ref("content");
    return ref
      .orderByChild("category")
      .equalTo('one-act-play' || 'ten-min-play' || 'full-length-play')
      .once('value')
      .then(snapshot => {
        const content = [];
        snapshot.forEach(childSnapshot => {
          content.push({
            id: childSnapshot.key,...childSnapshot.val()
          });
        });
        dispatch(setContent(content));
      });
  };
};
