Defining a query

  • Free search Select on words or part of words by typing a character string.
  • Pull down lists Select an item from the pull down list by clicking on this item
  • dates and numbers type a correct date (yyyy[mm][dd], month and day are optional) or a number and select < (before date or smaller than number) or > (after date or higher than number)

After defining your query you can indicate in which order the selected items should be displayed on your screen by selecting an item from the order by pull down list.
