What it is and what it does
zope.index is a collection of indexing data structures designed for use with Zope catalogs. It provides four main index types: field indices for orderable values, keyword indices, topic indices, and text indices with pluggable lexicon, splitter, and normalizer components. The package sits in the Zope ecosystem and depends on BTrees for tree storage, persistent for object persistence, and zope.interface for interface definitions.
Developers use zope.index when building catalog systems that need to efficiently search and retrieve objects by various criteria. It's primarily relevant for Zope-based applications or systems that adopt the Zope catalog pattern. The package is actively maintained, supports Python 3.10 through 3.14, and has no known security vulnerabilities.
Use it for
- Index orderable fields (dates, numbers, strings) in a Zope catalog for range queries and sorted retrieval
- Build keyword-based search indices for tagging and multi-value attribute lookups
- Create full-text search indices with custom tokenization, normalization, and lexicon handling
- Implement topic indices for hierarchical or categorical object classification in catalog systems
