Products.AdvancedQuery Flexible high level search construction and execution. For Zope 2.11 and above. AdvancedQuery ============= ``AdvancedQuery`` is a Zope product aimed to overcome several limitations and bugs of ``ZCatalog``'s native search function. Like ``ZCatalog`` search, it supports elementary index searches. While ``ZCatalog`` can combine such elementary searches only by "and", ``AdvancedQuery`` allows to arbitrarily combine them by ``&`` (and), ``|`` (or) and ``~`` (not). Besides, it supports an extended range of elementary queries, such as matching, indexed queries, literal result sets. Finally, it supports incremental filtering. ``AdvancedQuery`` also extends the sorting capabilities of ``ZCatalog``. ``ZCatalog`` supports efficient index based sorting on one level. ``AdavancedQuery`` supports sorting on arbitrary levels of field indexes. Furthermore, sorting is performed incrementally -- only as far as the result is accessed. This can drastically speed up sorting. Finally, ``AdvancedQuery`` can sort based on query based ranks. Unlike ``ZCatalog`` which simply ignores hits for which it does not have a sort value, ``AdvancedQuery`` sorts such hits at the end of the respective list. ``AdvancedQuery`` works best when used together with ``Products.ManagableIndex`` and ``dm.incrementalsearch``. Some of its features depend on these products, e.g. matching and incremental filtering. Furthermore, these additional components can speed up queries by several orders of magnitude.
