membphis opened a new issue #961: doc(FAQ): how to use regex to match uri. 
URL: https://github.com/apache/incubator-apisix/issues/961
 
 
   Currently, only the `path` in a route can be indexed. It supports full matching and prefix matching.
   If you want to support regular matching, you need to use the `vars` of the route.
   
   For example, to match this request: `/api/module/{code}/{param}`
   
   ```lua
   local rule = {
       paths = {"/api/module/*"},
       vars = {"uri", "~~", [[/api/module/{\w+}/{\w+}]]},
   }
   ```
   
   ----
   
   目前路由中只有 path 字段是可以被索引的，它支持全量匹配和前缀匹配。
   如果要支持正则匹配，需要通过路由的 `vars` 实现。
   
   比如要匹配这种请求：`/api/module/{code}/{param}`
   
   在 apisix 中需要这么写：
   
   ```lua
   local rule = {
       paths = {"/api/module/*"},
       vars = {"uri", "~~", [[/api/module/{\w+}/{\w+}]]},
   }
   ```
