Lucene (via SOLR and Elasticsearch) in an Academic Library

What do you like best?

Full text indexing and faceting controls are Lucene's true strength. You can easily index data based on a schema and immediately search across the whole index with blazing speeds. Sharding allowed for the index to be load balanced and mirrored across multiple back end nodes, providing a fault-tolerant search system. The buy-in from administrators was fairly easy as many of the top federated search engines within the academic library space are powered in some way by Lucene.

What do you dislike?

The setup is not trivial for vanilla Lucene. It helps to use something like SOLR or Elasticsearch that sits on top of Lucene to allow for your applications to easily interact with the backend. SOLR provides a great API (with XML and JSON output) for indexing and retrieving data. The statistics capability are the time we used it had a lot of room for improvement.

Recommendations to others considering the product

Considering coupling Lucene with something like SOLR or Elasticsearch in order to simply the indexing and retrieval of documents, as well as speeding up your development lifecycle.

What business problems are you solving with the product? What benefits have you realized?

The full text search and faceting enabled our library to move into the 20th century in terms of providing a full-featured search tool to our patrons. We used Lucene in conjunction with SOLR to index and expose our metadata from a variety of sources, including MARC, EAD, and HTML data. We eventually incorporated Elasticsearch into the mix to deal with unstructured JSON data (as it can operate without an official schema).

Great for improved search speed and relevance

What do you like best?

Lucene has allowed us to greatly improve our search performance and relevance, by easily indexing all of our data, and with very little configuration for the search we were able to greatly improve how the search product was delivered to our customers.

What do you dislike?

The lucene indexes on their own are difficult to maintain and search without experience, to make the most of them they need to be combined with SOLR, this also adds additional functionality which may bloat the application if it is not needed.

The tool that the SOLR addition of Lucene provides needs improvement, although it works and does its job and was difficult to set up and get to work in a large scale production environment.

Recommendations to others considering the product

It takes little effort to create a prototype search using lucene with SOLR, in which you will immediately see the benefits out of the box, with a large amount of additional features to further improve it.

What business problems are you solving with the product? What benefits have you realized?

We had a slow and expensive database cluster containing multiple servers to cope with traffic and speed requirements, we needed something cheaper, faster and more relevance to our search. Moving to Lucene provided this.

Great Product to Improve search

What do you like best?

Lucene has vastly improved our in house document search, both with Speed and relevance. After indexing the documents using the built in feeder, there is a great number of ways to manipulate how you break down your data and improve the way you search, using the SOLR interface makes it easy to run queries on data. It was also able to provide a geographical search based on lat/long of the data. Even running lucene without any modifications to the config we were able to immediately see an improvement in speed and relevance

What do you dislike?

The in built feeder was a bit difficult to configure and get working, and even when it was working it was very slow and would often stop working for no apparent reason, after looking into it further we were made aware that this is not meant for production use.

Recommendations to others considering the product

You will instantly see a vast improvement on your search experience using Lucene.

What business problems are you solving with the product? What benefits have you realized?

We have a large number of documents that require end users to search using keywords and locations, previous attempts using other methods required a lot more preprocessing of the data and was very slow.

I dont' like Lucene because of its incomplete implementations.

What do you like best?

I like Lucene because it's a search engine implemented in Java. Java is a easy-to-understand language.

What do you dislike?

I don't like Lucene because of its incomplete implementations, especially for recent state-of-the-art retrieval approaches. When I compare it with the Lemur toolkit, it misses several components.

Recommendations to others considering the product

If you want to implement everything from scratch, Lucene might be a good system!

What business problems are you solving with the product? What benefits have you realized?

I am doing research in the field of information retrieval. I am currently solving the problems regarded to the query modelling.
