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
Human beings search more and more. Continuing to treat search as some mystical voodoo is untenable and must stop.
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.
Traditional search engines and word2vec have their limitations for search relevance. Pt 2 of our series on BERT.
In which we take advantage of Solr's scripting update capability to turn Solr into an OCRing blackbox!
A relevant search result helps users take further steps, make good decisions, and supports their ability to formulate better, more informed, queries.
In which we deal with learning that sometimes you don't get to use the latest version of Tesseract...
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).
How to convert the _default managed schema in Solr v8.3.0 to the classic schema of yesterday
We explore what the basic unit of your search system should be. What *should* your document be? What 'result' in the SERP UI best satisfies your users?
In which we deploy Tika and Tesseract as a API in Solr, exposed via the /extract handler!
In which we explore how to deploy Tika and Tesseract as a stand alone service. And tie it into Solr via Payloads...
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.
My notes taken during the Haystack EU 2018 in Berlin, Germany, on October 28th.

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.

Haystack Europe is the conference for improving search relevance. Haystack Europe is the no-holds-barred conference for organizations where search, matching, and relevance really matters to the bottom line.
Doug Turnbull talks about Conversion Models: A Systematic Method of Building Learning to Rank Training Data and René Kriegler talks about Query Relaxation.
Don't be afraid of running Tesseract and Tika in your Solr cluster if...
Eric & Dan from OSC talk about OCR & Solr Payloads and Florian from Mimecast shows us how to index billions of log lines a day, and the usual Q&A and networking
How we hosted and ran a Lucene Hackday in Washington DC the week of the Activate conference, and what attendees considered and achieved during the day
TALMIRI is a symposium to bring together talented early-stage researchers, academics and information retrieval industry with invited speakers in an iconic location in Bedfordshire, UK. Practioners and researchers, in particular but not exclusively PhD/MSc students and early-stage researchers, are invited to present (as poster or demo) their exciting search and information retrieval related work to IR experts and industry. Charlie Hull of OSC will be presenting on Working in Open Source Search, giving attendees an insight into the sort of projects and technology he has dealt with over a 20 year career in search.
Our next training event, Relevance Cornucopia🦃, we'll add the missing piece to the manual tuning & learning to rank picture: Natural Language Search. Come learn to build relevance that can be both optimized by machine learning AND understands user's natural language.
Search systems struggle to balance diversifying the result set to match likely intents vs ranking against one well understood intent.
