Liferay 搜索容器中的搜索框

大家好，图片上的人在这里！ 我只是想问一下，当用户在搜索框中键入一个名称时，应该显示特定的字段。我把我的view.jsp代码也放在这里

Vuew.jsp

.包装纸{
文本对齐：居中；
}
.按钮{
位置：绝对位置；
最高：20%；
}



员工推荐

是的，一旦完成，我们可以为此编写动态查询并重建服务。 完成此操作的步骤。 1:-首先，我们必须在localserviceimpl.java中编写一个动态查询，以便在重建服务时，它将在localserviceutil.java中生成方法 2:-我们可以使用显示项在搜索表单搜索容器中调用此方法。 3:-我们可以使用任何键值轻松搜索
