  The High-Level Queries panel offers the user a simple interface to perform some predefined complex queries, setting SQL conditions upon multiples database tables at once.</p>
<p><br>

  <br>
  <br>
</p>
<p>The left part of the window presents the list of all supported high-level queries; in the figure there are 2 available HLQs, respectively looking for all AOs with a given name and initial time greater than a given t0, and AOs with a given name and included among two given times. After the selection of the desired query on the list, the button 'Set' will allow to adjust the proper settings.</p>
<p>All the settings associated to the selected HLQ are displayed  in the right part of the panel; in the example of the figure they are the name the queried AOs must match, and the upper and lower limit  times of its time-series data (meaning the object must contain tsdata  comprised among these given times).</p>
<p>Executing the query (click the 'Execute query' button) produces the same results as the 'Query' panel shown before.</p>
