This package provides an queryparser, querybuilder and extra helper tools, to parse stored queries to actual results, used in new style collections. It includes a registry reader which reads operators, values and criteria from the Plone registry.
The 1.1.x series is intended for usage with Plone 4.3 and up. It depends on plone.batching, which ships with Plone 4.3 but may cause problems with Plone 4.2.
For use with Plone 4.2.x, use versions < 1.1.0.
Date ranges now use the _betweenDates handler, which is much more forgiving of empty field values, defaulting to an all-encompassing date range if neither value is provided, an "everything after" range if only the start date is provided, and a min/max range if both are provided.
