Quepid Migrates from Flask to Rails

Youssef Chaker — November 23, 2015

We recently worked on moving Quepid from a Python backend to a Ruby backend, something Joel Spolsky would frown upon. Here's why.

InternetSummit 2015

BM25 The Next Generation of Lucene Relevance

Doug TurnbullOctober 16, 2015

There's something new cooking in how Lucene scores documents. Instead of the traditional "TF*IDF," Lucene just switched to something called BM25 in trunk. That means a new scoring formula for Solr (likely Solr 6) and Elasticsearch down the line.


October 15-16

*The* conference focused on Solr, we've made the pilgrimage since 2010

OSC is Proud to Support Charlottesville Women in Tech (CWiT)!

Becky BillingsleyOctober 13, 2015

When the Charlottesville Women in Technology (CWiT) team first contacted Opensource Connections (OSC) about whether or not we wanted to sponsor CWiT for the year, to be honest I knew very little about the details of gender inequality in Science and Technology and even less about ways to help address that inequality.

Announcing Quepid For Elasticsearch

Doug TurnbullSeptember 25, 2015

Good news! We're proud to announce our test-driven search toolbench Quepid now supports Elasticsearch. Quepid helps by bringing test-driven principles to tuning search results -- what we call Test-Driven Relevancy. It helps define what good search results by incorporating your own business expertise from colleagues that know users the best

Cassandra Summit

September 22-24

Returning for another year, John, Matt, Eric, and Chris will all be at Cassandra Summit, sharing war stories from our C* projects for the Federal Government and Commercial clients

Elyzer: Step-by-Step Elasticsearch Analyzer Debugging

Doug TurnbullSeptember 22, 2015

I love stringing together custom analyzers to solve my search problems. Analyzers control how search and document text are transformed, step-by-step into individual terms for matching. This in turn gives you tremendous low-level control of your relevance. Yet one thing has always bugged me with Elasticsearch. You can't inspect the step-by-step behavior of an analyzer very easily. You have the _analyze API, which helps a great deal see the final output of the lengthy analysis process. But you can't pry into each step to see what's happening.

The Simple Power of Elasticsearch Analyzers

Doug TurnbullSeptember 18, 2015

In Chapter 4 of Relevant Search, we talk a LOT about Elasticsearch analyzers. Without analyzers, your search engine would be a rather unintelligent string comparison system instead of a smart, powerful search engine. Analyzers are the text-processing pipeline that feed the search engine's core data structures, controlling whether two tokens (basically words) match during a search.

Quepid Scores with Custom Scorers!

Becky BillingsleySeptember 1, 2015

Starting in the summer of 2015, users can create their own scorer to accommodate any scale of ranking results and make their own custom scoring algorithm that that work best for their situation.

Cassandra Day: New York

Aug 19

We will be sharing war stories about building always on always available discovery systems using Cassandra

Splainer: A Solr Developers Best Friend

Doug TurnbullJuly 24, 2015

Do you know about Splainer? It's our handy-dandy, free and open source tool for working with Solr search results. It's become my favorite go to tool for tweaking a specific Solr query. Let's face it: nobody likes working with Solr in their browser's URL bar. It's a royal pain.

Copy & Paste your git status logs like a pro

Daniel BeachJuly 10, 2015

It’s time to fill out your timesheet, again. You’ve put in a full week of work but remembering everything you’ve accomplished can be difficult when you’re jumping between projects. What if you could just quickly copy your git commits for the week and be done?

Log Every Document Added To Solr

Doug TurnbullJuly 2, 2015

I often want to intercept the Solr docs in a format I can use offline. Clients have complex ingestion systems. I shouldn't need to have the full ingestion apparatus to do some Solr work. With documents offline, I can script something simple and stupid that throws documents at Solr to test my search relevancy work without having the full system at hand to populate Solr.

VLDS Insights 2015

Jun 30

VLDS is the Virginia Longitudinal Data System, providing educational and workforce training data to improve public education. Eric will be looking at how we can help improve educational outcomes.

Improving on Git Flow: Code Reviews

Doug TurnbullJune 29, 2015

Something amazing happened today on our Quepid project. We did a code review. Instead of trying to extract value from reviewing pull requests in isolation, we realized actually talking to each other was the only way to move the dial on understanding each other's work.
