Improved Search With Lucene 4

Robert Muir is a Lucene/Solr Committer and PMC Member, and a Senior Staff Engineer at Lucid Imagination.

This talk describes how you can practically apply some of Lucene 4's new features (such as flexible indexing, scoring improvements, column-stride fields) to improve your search application.

The talk will give a brief description of these new features and some example use-cases, to address practical use cases you can try yourself in and around the new features now available in Lucene 4. We'll cover application of functions where you can configure Solr to:

Set up the schema to use Pulsing or Memory codec for a primary key field Not use a separate spellcheck index, controlling character-level swaps from the query processor Sorting with a different locale Per-field similarity configurations, such as using a non-vector-space algorithm
