Index Pruning

Static Index Pruning Tools

This package provides a framework for pruning an existing index into a smaller index while retaining visible search quality as much as possible.

An index can be pruned in several levels:

1. Remove stored data: see StorePruningPolicy
2. Remove terms data: see TermPruningPolicy

Pruning can be applied programmatically via a PruningReader or with the static tool PruningTool.
