-==== The Smart query editor ====+==== Introduction ====
  
-In this section you'll learn how to use the //Smart Query Editor//, a special editor that allows you to compose queries that exploit corpus annotation (things like part-of-speed and lemma). +To begin this tutorial, follow these steps:

-To open the Smart Query Editor follow these steps:+
  
   * start Carcass and connect to the server   * start Carcass and connect to the server

   * click on //UkWaC 1//   * click on //UkWaC 1//
  
-At this point the three main query editors (**Simple**, **Smart** and **Expert**) will be open.+==== Using the asterisk ====
  
-Select the **Smart query editor**.+Let's say you want to look for words that begin with "under" (such as "under", "underneath", "understand", etc.)
  
-{{ :sarcophagus:carcass:tutorials:advanced:010_select_smart_editor.png?950 }}+You can easily do this in Carcass using the asterisk.((the correct term for this is actually "Kleene star operator", but we'll just call it asterisk to keep things simple)) 
 + 
 +Type this query in the //Simple Query// box and click on //Submit//: 
 + 
 +<file> 
 +under* 
 +</file> 
 + 
 +The query will return results like "under", "underpinning", "underside" etc. 
 + 
 +**N.B.**: this simplified use of the asterisk only applies to the //Simple Query Editor//, the //Smart// and //Expert// query editors use a slightly different syntax. This may change in the future.

 +==== The Smart Query Editor ==== 
 + 
 +In this section you'll learn how to use the //Smart Query Editor//, a special editor that allows you to compose queries which exploit corpus annotation (things like [[wp>part-of-speech]] tags and [[wp>lemma (morphology)|lemma]]).

 +Select the **Smart Query** Editor.
