"IncrementalSearch" is an efficient incremental search engine supporting 'and', 'or' and 'not' queries. Unlike Zope's standard search engine, it determines hits incrementally, one at a time. It interleaves index lookup and thereby prevents the creation of large intermediate result sets and touches (almost) as few index blocks as possible. This can significantly reduce load time. Measurements comparing an incremental PathIndex with a standard Zope PathIndex showed speedups between 0.8 upto 50.

It now comes out of the box with Field-, Keyword-, Range-, Path- and WordIndexes. Unlike other index implementation which support pattern matching only for TextIndex, Managable Field-, Keyword- and WordIndexes support both glob as well as regular expression matching provided the indexed values are strings. New in version 0.10: * it now uses "IncrementalSearch" if available * an improved PathIndex with a new "depth" search option. While "level" controls the distance of the search path from the beginning (as with the standard PathIndex), "depth" controls its distance from the end (in a symmetrical way). * Fixes for unicode values Download: <http://www.dieter.handshake.de/pyprojects/zope#ManagableIndex> "AdvancedQuery" is a Zope product aimed to overcome several limitations of ZCatalog's native search function. Like ZCatalog's search, it supports elementary index searches. While ZCatalog can combine such elementary searches only by "and", AdvancedQuery allows them to be combined arbitrary with & (and), | (or) and ~ (not). While ZCatalog supports an efficient sorting via an index on one level, AdvancedQuery supports sorting via any level of (field) indexes. Moreover, it sorts the result incrementally -- only as far as you access your result. This can drastically speed up the time required for sorting. It uses Python's generators for this (and thus requires Python 2.2 or better). New in version 0.6: it now used "IncrementalSearch" if available.

This is in protest against plans of the Council of Ministers to make logic (general ideas outside of a concrete technical system) and especially software patentable in Europe.
