MemeFinder: No Dictionaries Needed

When I was working for the related content provier Sphere, I was presented with an interesting problem. We were using Apache Lucene back before using Lucene was cool, and overall it worked very well. However, there were some contextual gotchas that were causing them trouble. Homonyms, in particular, were causing un-related results to appear. Being […]

"Stateful" persistence in a Fusion JavaScript Pipeline

One of the most useful features of Nashorn JavaScript in Lucidworks Fusion is the ability to access Java objects within the context of your JavaScript stage. Often times, you’ll want to maintain the state of a variable; or maybe you want to only make a REST call once, and store the result. You can certainly […]

Making an Authenticated REST Call in a Fusion Pipeline

REST… easy! There are times you just need to reach outside the box and do something. Sometimes that something would be launching a process, or perhaps making an alternate query, or even calling some third party API, like ESRI. If the REST call you’re making doesn’t require authentication, you can do that with a plain, […]

Extracting Values from Element Attributes using Jsoup and a JavaScript Stage

To accomplish this: […]

Overriding the Query Pipeline, Pt III

When we last left our rogue query pipeline in Pt II, we had made our Solr query and had tucked the response into a JSON object.  This call was made from our “main” function, which is incidentally the last function — an anonymous function — declared at the end of your stage.  For example: function […]
