有关solr的电商应用的问题_course

亲们，请教一个问题 现在我有这样个需求，电商网站，要根据关键字搜索商品，要制作商品导航栏，但是这个导航栏是动态的 要根据关键字动态显示 比如关键字是和笔记本有关的，那么导航栏要有CPU型号，显卡型号等等参数选择 如果关键字是和服装相关的，那么导航栏要有款式，尺码，等等参数选择 要有个公共的导航，比如品牌，分类，价位，无论什么类型的商品这个都要有 我知道用facet，facet只能根据固定的字段facet，不能根据商品类型动态facet 用的技术是solr，请问有什么办法，或者思路能实现这个需求呢。。

lucene/solr选择哪个版本_course

如题。 查看官网[lucene官网](https://lucene.apache.org/ "lucene官网")，对Apache发布的版本顺序有点摸不着头脑。 24 October 2017, Apache Lucene 5.5.5 and Apache Solr 5.5.5 18 October 2017, Apache Lucene 6.6.2 and Apache Solr 6.6.2 17 October 2017 - Apache Lucene 7.1.0 and Apache Solr 7.1.0 。。。 怎么时间上越新的版本却是5.5.5，早些的却是6.6.2？7.1.0？ 难道是Apache在管理多个系列（ex：5.x,6.x,7.x）的lucene/solr吗？ 发布的都是每个系列最新的版本？ 如果是的，那么作为初入学习Lucene，选择哪个版本比较好呢？

【Solr-SolrJ】一个关于Solr 和 SolrJ 实现边界检索（range query）的问题_course

在solr中可以实现边界查询（range query），具体已经在 http://wiki.apache.org/solr/SolrQuerySyntax 有说明 例如： 假设我的索引包含以下三个字段： title, x, y ，且每个结果集都包含 title，x，y 1. 如果想检索title字段，并且检索结果满足 10 < x < 100 ，通过solr实现： http://localhost:8983/solr/select?q=x:[10 TO 100]&fl=title 2. 但是如果title字段，并且检索结果满足 10 < x < 100 且 20 < y < 60，采用solr或者SolrJ就不知道怎么实现了？ 求懂solr或者SolrJ的人给个解决办法 enzhaohoo@gmail.com 多谢
