Did you know that LinkedIn currently has the ability to deliver incredibly powerful search functionality to its users – WELL beyond what we all have access to now?  What am I talking about?

I’m excited to tell you, but quite honestly, I actually can’t believe it’s taken me this long to put 2 and 2 together. Have you ever really watched the video clip below that you can find on  LinkedIn’s Learning Center as well as on YouTube?

If you ignore the information regarding the new features and pay close attention to the video, you can hear Esteban talk about how LinkedIn is always on the lookout for talented Lucene Open Source engineers and watch him search for them. Lucene is an open source text search engine that I’ve written about in multiple posts for its advanced search functionality, including extended Boolean.

LinkedIn uses Lucene as their Text Search Engine

When I first watched the video, I never gave the Lucene stuff a second thought because LinkedIn doesn’t actually offer any of Lucene’s truly advanced search functionality – LinkedIn doesn’t even support root-word/wildcard searching, let alone extended Boolean search. I figured if they were already using Lucene for their text search engine they would offer all of Lucene’s search functionality, which they don’t.

Then I watched the video again the other day (not exactly sure why) and I it made me curious. Had they already implemented Lucene, or were they looking to do so? I did some research to see if I could confirm a link between LinkedIn with Lucene (pun intended).  Although TechCrunch reported that LinkedIn upgraded its people search, they failed to mention the technology behind the upgrade. I was then able to dig up an article that verified that LinkedIn had implemented Lucene as their text search engine.

So What Can LinkedIn Do With Lucene?

I’m glad you asked – be prepared to be amazed!  Continue reading →
