搜索容器中的搜索框

Question

大家好，根据搜索器中的搜索框图片是在这里！我只是想问一下，当用户在搜索框中输入名称时，应该显示特定的字段。我正在将我的view.jsp代码也放在这里？

<%@ import="com.proliferay.servicebuilder.service.BlobDemoLocalServiceUtil"%> <%@ taglib uri="0“prefix="portlet"%> <%@ taglib uri="http://liferay.com/tld/aui”prefix="aui"%> <%@ taglib uri="http://liferay.com/tld/ui“prefix=”prefix=“%>

是的，我们可以编写一个动态查询并重建服务。这样做的步骤。1:-首先，我们必须用localserviceimpl.java编写动态查询，以便在重新构建服务时，它将生成localserviceutil.java 2中的方法：-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:-我们可以很容易地使用任何键值进行搜索。
