I am trying to display certain features in a shapefile-based layer using QGIS. I have found the subset function in the properties panel, which does exactly what i want, but is too tedious given that I have to manually sift through a large number of features. Is there a quicker way to do this?

I am using both shapefiles and postGIS best, dietmar

In QGIS you should be able to filter your data with an SQL expression in the Query Builder dialog. Just right click your layer in the table of contents and select "Query".
