Jus to add to this, what was done as a test for the filter encoding is 
to convert the OGC filters (all logical,  comparison, spatial) into 
common expressions and used it to set the filter element on the layer 
and run the query. This is a big improvement in terms of code cleaning 
and optimization (when compared to running several queries for one ogc 
filter and then merge the resulting queries).  This works now for 
mapserver shape type layers. The ultimate goal is to have all underlying 
drivers to be able to convert all common expressions into appropriate 
queries.
