Lucene and Solr are the most widely deployed search technology on the planet, powering sites like Twitter, Wikipedia, Zappos, and countless applications across a large array of domains. Lucene and Solr also contain a large number of features for solving common information retrieval problems ranging from pluggable posting list compression and scoring algorithms to faceting and spell checking.

Increasingly, Lucene and Solr also are being (ab)used to power applications going way beyond the search box.…

Even though Solr can run without causing any trouble for long periods of time, it is very important to monitor and understand what is happening in your cluster.

In the session, “Administering and Monitoring SolrCloud Clusters” by Rafal Kuć, Consultant and Software Engineer at Sematext Group, you will learn how to use various tools to monitor how Solr is behaving at a high level, but also on Lucene, JVM, and operating system level. …

The Lucene/Solr Revolution session, “Sidecar Index – Solr Components for Parallel Index Management,” by Andrzej Bialecki at LucidWorks, presents a set of Solr components for easy management of “sidecar indexes” – indexes that extend the main index with additional stored and/or indexed fields. Conceptually this can be viewed as an extension of the ExternalFileField or as a static join between documents from two collections. This functionality is useful in applications that require very different update …

The customers in the Intelligence Community and Department of Defense that ISS services have a big data challenge. The sheer volume of data being produced and ultimately consumed by large enterprise systems has grown exponentially in a short amount of time. Providing analysts the ability to interpret meaning, and act on time-critical information is a top priority for ISS.

In the Lucene/Solr Revolution session, “Shrinking the Haystack using Solr and OpenNLP,” Wes Caldwell, Chief …

Relevance is a critical aspect of a successful implementation of a search solution, and tuning it to get it right is essential to the success of search projects. During the Lucene/Solr Revolution session, “Solr Relevance Tuning Simplified,” Daniel Ling, Senior Architect at Findwise, will share some best-practices for working with relevance, including three uses case examples of the impact of customized relevance based on scenarios from the media industry and an intelligence agency, as …

Lucene’s arsenal has recently expanded to include two new modules: Index Sorting and Replication. Index sorting lets you keep an index consistently sorted based on some criteria (e.g., modification date). This allows for efficient search early-termination as well as achieving better index compression. Index replication lets you replicate a search index to achieve high-availability and fault tolerance, as well as to take hot index backups.

Solr is a powerful search engine, but creating a custom user interface can be daunting. In this fast paced session at Lucene/Solr Revolution, Daniel Beach, Search Application Developer at OpenSource Connections, will present an overview of how to implement a client-side search application using Solr.

Using open-source frameworks like SpyGlass can be a powerful way to jumpstart your development by giving you out-of-the box results views with support for faceting, autocomplete, and detail views. …

If you want to search in a multilingual environment with high-quality language-specific word-normalization, if you want to handle mixed-language documents, if you want to add phonetic search for names, if you need a semantic search that distinguishes between a search for the color “brown” and a person with the second name “brown”… in all of these cases you have to deal with different types of terms.

During this session at Lucene/Solr Revolution, Christoph Goller, …

This session by Erik Hatcher, Senior Solutions Architect at LucidWorks, will introduce and demonstrate several techniques for enhancing the search experience by augmenting documents during indexing.

First he will survey the analysis components available in Solr, and then he’ll delve into using Solr’s update processing pipeline to modify documents on the way in. The session will build on Erik’s “Poor Man’s Entity Extraction” blog post.

This intermediate level session will take place …

While Solr and Lucene were originally written for full-text search, they are capable and increasingly used for Analytics, as Key Value Stores, NoSQL databases, and more.

In this Lucene/Solr Revolution session Otis Gospodnetić, President of Sematext, will describe their experience with Solr for Analytics. More specifically, he will describe a couple of different approaches they have taken with SolrCloud for aggregation of massive amounts of performance metrics. He’ll share their findings, and compare SolrCloud …
