    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:

  Remove stored data: see StorePruningPolicy
  Remove terms data: see TermPruningPolicy

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