AdvancedQuery is a Zope product for flexible queries
against "ZCatalog" or "CatalogTool".
Queries can be arbitrarily combined with "and", "or" and "not".
All index types are almost fully supported (exception: relevance
sorting of TextIndexes).
AdvancedQuery supports efficient incremental (lazy) multi-level sorting via
FieldIndexes. This means, you can sort via e.g.
"sort_on=(('Date','desc'), 'portal_type', 'id')". For large
result sets, sorting is performed incrementally,
only as far as you access the result. This can drastically speed up
AdvancedQuery is especially efficient for "ManagableIndex"es
New in version 0.2:
* optimization of descending sorting using new

Note: This may be the last version with its current open source
unrestricted use license. I consider whether I will expressly
forbid the use of my software by institutions of the
European Union (Councel of Ministers, Commission, Parliament, ...).
This is in protest against a recent decision of the
Councel to make software patentable. This decision
ignores a Parliament vote that pleaded to keep logic (algorithms,
business rules) un-patentable.
