 ====== Carcass Advanced Tutorial - Part 2 ====== ====== Carcass Advanced Tutorial - Part 2 ======
  
-==== Smart Query Editor ====+==== More on the Smart Query Editor ====
  
 +Note also that the query you just submitted was added to the //Query history//, just like the simple query you submitted using the //Simple Query Editor//.
  
 +Now let's try a different query:
  
-====== ======+  * first of all, reset the previous query by clicking on ''Clear form'' 
 + 
 +\\ 
 + 
 +{{ :sarcophagus:carcass:tutorials:advanced:070_clear_form.png?950 }} 
 + 
 +\\ 
 + 
 +  * then fill out the form like this: 
 +    * Position 1: in the //Lemma// box type ''apply'' 
 +    * Position 2: in the //Part of speech// drop-down list select ''Determiner'' 
 +    * Position 3: in the //Part of speech// drop-down list select ''Noun'' 
 +    * click on ''Submit'' 
 + 
 +\\ 
 + 
 +{{ :sarcophagus:carcass:tutorials:advanced:080_smart_query_2.png?950 }} 
 + 
 +\\ 
 + 
 +This query returns all occurrences of the the verb "apply" (in all its inflected forms), followed by a determiner and a noun. 
 + 
 +\\ 
 + 
 +{{ :sarcophagus:carcass:tutorials:advanced:090_query_2_results.png?950 }} 
 + 
 +\\ 
 + 
 +There might be errors in the results (e.g. sometimes the second word will not be a determiner or the third will not be a noun): they are due to inaccuracies in the pos-tagging of the corpus. This kind of errors are to be expected when dealing with automatically tagged corpora (such as the //UkWaC// corpus we are using in this tutorial). 
 + 
 +Here again, sorting results by match could be useful. 
 + 
 +==== Optional positions ==== 
 + 
 +In the smart query, it is also possible to specify that a particular position is optional. 
 + 
 +For example, we could try to look for the same pattern as before ("apply" followed by a determiner and then by a noun) and specify that we want the determiner to be optional. 
 + 
 +We will modify the query we just submitted by ticking the **position is optional** checkbox in //Position 2//. If you didn't modify anything after submitting the last query, all you have to do is tick the checkbox marked by the red arrow: 
 + 
 +\\ 
 + 
 +{{ :sarcophagus:carcass:tutorials:advanced:100_smart_query_3.png?950 }} 
 + 
 +\\ 
 + 
 +This query will return concordances like "apply makeup" and "apply the policies" because we told the program that **position 2 was optional**. 
 + 
 +If we were interested in finding out what you can do with a "proposal" in English, we could try a query like this 
 + 
 +  * click on ''Clear form'' to reset the form 
 +  * Position 1: in the //Part of speech// drop-down menu select ''Verb'' 
 +  * Position 2: tick che //position is optional// checkbox and then select ''Determiner'' in the //Part of speech// drop-down menu 
 +  * Position 3: in the //Lemma// box type ''proposal'' 
 + 
 +**N.B.**: this query will probably take more than a few seconds to complete. 
 + 
 +\\ 
 + 
 +{{ :sarcophagus:carcass:tutorials:advanced:110_smart_query_4.png?950 }} 
 + 
 +\\ 
 + 
 +The query will return concordances like "made proposals", "reject the proposal", etc. 
 + 
 +In the [[sarcophagus:carcass:tutorials:advanced_3|next part]] of the tutorial, you'll learn about the //Expert query editor//.
