Hi, i just started working with paraview python scripts, and i wanted to know if their was a way to query multiple cells based on their id
similar to this in the editor 
i tried something like this but it didn’t work
paraview.simple.SelectCells(query=“id==1 | id==2 | id==3”)
The following should work:
# create a query selection
paraview.simple.QuerySelect(QueryString='((id == 1) | (id == 2) | (id == 3))', FieldType='CELL')
The easiest way to figure this out is to use the Python tracing capabilities: Tools > Start Trace, check Show Incremental Trace in the Trace Options dialog, and then use the Find Data dialog to do the query.
