Java JSP搜索结果过滤/优先级排序

时间：2014-02-28 14:35:04

标签： java html jsp search

请关注我，因为我不是程序员，但我有一个公司内部网搜索站点，它在特定数据库中搜索对象并返回结果表。我所关注的元数据标签基本上是“类型”，“名称”和“修订版”。在这个数据库中，我们可能会使用“Type A”，“Type B”和“Type C”捕获相同的文档，其中Name和Rev对于这三个都是相同的。

目前，当您通过htm站点提交“名称”搜索时，JSP配置为返回所有类型，但仅返回最新/最新版本。我想修改编码（最好是在htm中，如果可能的话），也要优先考虑类型，以及它们是否像修订版一样按顺序排列（转1,2,3等）。

例如：如果搜索找到两个具有相同名称和rev的项目，我只希望显示类型A并忽略类型B和C. 如果类型A不存在，或者没有有效的文件链接，则搜索结果应仅显示类型B. 如果A和B不存在，再次显示C型。

如果可以在htm函数或变量中实现这些想法吗？或者这是否必须在htm引用的JSP中进行编码？
