Deploying Solr in complicated multi-region environments & Search at BBC Online at the London Lucene/Solr Meetup
Konstantin Perikov of EPAM with a review of different ways to deploy Solr in complicated multi region environments and Andy Webb on Search at BBC Online
Opening up search is an ethical imperative
Human beings search more and more. Continuing to treat search as some mystical voodoo is untenable and must stop.
Why you should submit a talk to Haystack, the Search Relevance Conference
Will my talk get chosen? Will attendees find it interesting? A chance to answer some of the questions you might have about submitting a talk to Haystack, the Search Relevance Conference.
What problem does BERT hope to solve for search?
Traditional search engines and word2vec have their limitations for search relevance. Pt 2 of our series on BERT.
Tika Tuesdays: Parsing Tika & Tesseract formatted HOCR output inside Solr ingestion pipeline
In which we take advantage of Solr's scripting update capability to turn Solr into an OCRing blackbox!
What is a 'Relevant' Search Result?
A relevant search result helps users take further steps, make good decisions, and supports their ability to formulate better, more informed, queries.
Tesseract 3 and Tika
In which we deal with learning that sometimes you don't get to use the latest version of Tesseract...
Demystifying nDCG and ERR
In this post, we unwrap the mystery behind two popular search relevance metrics, and discuss their pros and cons. Our subjects for this exercise are Normalized Discounted Cumulative Gain, and Expected Reciprocal Rank, commonly acronymified as nDCG and ERR. We'll start with some refresher background, visualize what these metrics actually look like, and paint a picture of how each can be either helpful or misleading, depending on the situation. Afterwards, you'll have a better understanding of their behavior and which ones to use when (and why).

It's time for Tika Tuesdays!
It's time for Tika Tuesdays! Three years ago I started messing around with OCRing documents with Tika, and today that process is relatively straightforward. This weekly series will share what I've learned.

Understanding BERT and Search Relevance
There is a growing topic in search these days. The hype of BERT is all around us, and while it is an amazing breakthrough in contextual representation of unstructured text, newcomers to NLP are left scratching their heads wondering how and why it is changing the field. Many of the examples are tailored for tasks such as text classification, language understanding, multiple choice, and question answering. So what about just plain-old findin' stuff? This article gives an overview into the opportunities and challenges when applying advanced transformer models such as BERT to search.
