Apache Lucene

Apache Lucene offers great full-text search library that makes it easy to add search functionality to a website or other applications. Lucene is ideal if you want low-level access to the indexes and its APIs. For general purposes, Apache Solr, the web application built atop of Lucene can be used instead. Apache Solr comes with caching, HTTP/ JSON APIs and a simple web administration console.

Google Search Appliance

The Google Search Appliance is well suited to most site search needs and it is possible to customize the front end seen by website visitors to produce a satisfactory basic interface with basic branding applied to it. However, in some situations it may be necessary to instead make API calls from a web page to retrieve search results and the format in which those results are returned might be a little more difficult to work with.

Pros

  • We found Apache Lucene to be extremely performant in querying large amounts of data and retrieving the correct files based on the metadata provided.
  • The online community offers great support for the product. Even though it is an open source tool, it is not difficult to find help online for it.
  • When we were creating a proof of concept application, we found that the software worked just as well, while being run locally on a resource-limited PC.

  • The GSA is able to organize collections of content in many different permutations, based on your needs.
  • The logs of searches and served results can offer insights into what visitors/customers are seeking, and whether they're finding what they need.
  • Default front-ends are relatively easy to set up - if they meet your needs.

Cons

  • We had difficulty porting the project to a cluster based environment on the cloud.
  • For our particular use case of retrieving documents based on text pattern matching, the program worked efficiently however, we did not find many resources for image pattern recognition based on their metadata.

  • It's my understanding that Google is ending support for the appliance soon. This is obviously an important consideration.
  • The administrator interface is far from easy to use.
  • There is a significant learning curve for new users.

Return on Investment

  • Being an open source project we did not have to pay any licensing fees for using Apache Lucene. It has greatly improved our search functionality in our web apps.

  • The GSA was not cheap. At all.
  • There has also been a cost associated with our need to switch to another site search solution in the near future, due to Google ending support for the sppliance.
  • That said, we have so much support content that we owed it to our customers to offer a comprehensive search tool to help them find the most relevant content - and of course Google are the masters of this. However, it's worth noting that the alogorithms used on the GSA are far older than those used on google.com.
