Lucene and Solr provide a number of options for query parsing, and these are valuable tools for creating powerful search applications. This presentation given at the 2013 Lucene Revolution will review the role that advanced query parsing can play in building systems, including: Relevancy customization, taking input from user interface variables such as the position on a website or geographical indicators, which sources are to be searched and 3rd party data sources. Query parsing can also enhance data security. Best practices for building and maintaining complex query parsing rules will be discussed and illustrated. Chief Architect Paul Nelson provides this compelling presentation.
