The graphical query editor offers a simple way to use all of the SaadaQL features. Queries can contain as much constraints as needed. Query strings can be directly refined by hand.

 The query editor

• The query editor is expended/collapsed by clicking on
• It has different tabs, active or not according to the curren t data category :
  • No query by position for table headers
  • No match pattern queries for dataset without relationships

• Query by position

• • Search positions can be either by name or by coordinates
  • Each new position must be added to the query by clicking on the blue arrow
  • Positions can be given as a TSV list of either coordinates or object names :

    #comment
    04:18:25.81+56:10:29.0
    17:33:21.00-32:34:12.0
    M33
    M34
    M35
    M36
    

  • Saada also supports search by polygonal regions.

• Query by keywords
  • You can stack as many keyword based constraints as you want on the query.
  • Constraints are edited one by one

• Refining the query by hand
  • The query string can be edited by hand in the Plain Text Query tab.
  • This breaks the synchronization with the widgets. Any action on any widget will override the modification done by hand.
