# Lucy::Docs::Cookbook(3pm)

Apache Lucy recipes.

## NAME

Lucy::Docs::Cookbook - Apache Lucy recipes.

## DESCRIPTION

The Cookbook provides thematic documentation covering some of Apache Lucy's more sophisticated features.  For a step-by-step introduction to Lucy, see Lucy::Docs::Tutorial.

### Chapters

- •

  Lucy::Docs::Cookbook::FastUpdates - While index updates are fast on average, worst-case update performance may be significantly slower. To make index updates consistently quick, we must manually intervene to control the process of index segment consolidation.

- •

  Lucy::Docs::Cookbook::CustomQuery - Explore Lucy's support for custom query types by creating a "PrefixQuery" class to handle trailing wildcards.

- •

  Lucy::Docs::Cookbook::CustomQueryParser - Define your own custom search query syntax using Lucy::Search::QueryParser and Parse::RecDescent.
