---------------------------------

             Summary: Supoort regular expression when query some timeseries or 
devices
                 Key: IOTDB-909
                 URL: https://issues.apache.org/jira/browse/IOTDB-909
             Project: Apache IoTDB
          Issue Type: New Feature
          Components: Core/Engine
            Reporter: Houliang Qi


Now, when querying the timeseries or devices, the engine supports prefix path,  
like:

_show timeseries root.sg1_

_show device root.ln.server1_

However, support there are some timeseries looks following:

_root.ln.server1.an_device1_

_root.ln.server1.an_device2_

_root.ln.server1.am_device3_

_root.ln.server1.am_device4_

The user may want to query the device by prefix "an", like the following 
statements:

show device _root.ln.server1.an*_

may be we can solve the problem by seperating the __ _an_device1_ to 
_an.device1_, however, I think its not user-friendly.

besides influxdb support regular-expressions[1], if we can support the 
function, it may be esaier for some influxdb's user transfer to iotdb.
