Upgrading a .NET Application with Solr and SolrNet

09 Jan 2020 by Xavier in General 2 comments tags: solr, solrnet
Today I took the task of updating a .NET application that I’ve had since sometime around 2013. I created this application with a few people at the time of .NET 4.0 and Solr 4.10, with its corresponding SolrNet. Today I moved it to Solr 8.4 and with .NET 4.7. There are a few interesting changes that you need to take into account, which I may expand at some point. But just in case, if you are in the same scenario, here are some upgrade tips for you to consider: #1 When you move from Solr 4.10 (and older versions) to 8.4, there are some changes to take into account The default field is now _text_ and not text Some types may have changed Default now is managed-schema, not schema.xml Some changes are required in solrconfig.xml So, what I did is downloaded, installed and started a Solr 8.4. Then I created a core bin\solr.cmd create -c <name> Next, I configured Solr so that I do not use schemaless mode. Use this link for more info: Switching from Managed Schema to Manually Edited schema.xml Don’t forget that besides changing the ClassicIndexSchemaFactory, you also need to disable schema guessing, which allows unknown fields […]

Welcome to Big Data TV – Or The One That Started It All

09 Dec 2018 by Xavier in Big Data, Big Data Series, Development, Enterprise Search, Hadoop, Pluralsight 0 comments
Hello and welcome, I am Xavier Morera and I am very passionate about helping developers understand enterprise search and Big Data. And today, I welcome you to the first post of the Big Data Inc Series (which will soon be joined with Big Data TV). So, you might be wondering… what is the Big Data Inc Series?  Easy. It is a series of bite size posts that explain enterprise search and Big Data. What is my objective? At a high level, each post will take between 5 to 7 minutes, and will provide an overview of one particular topic – and only one – to give you enough information to understand what is the purpose of a particular platform, language, project or anything else that touches enterprise search and Big Data Why am I doing this? First of all, I am really passionate about search and Big Data… like a kid on Christmas day. I do have to agree that I have my preferred platforms, languages, and projects.  However, it does not hurt to have an idea of what each one is about. Also, why are the posts so short? Well, I could go on and on for hours – […]

Learning Apache Solr – Online Training – Instructor Led Training – Book

05 Dec 2018 by Xavier in General 0 comments
Search is one of the most misunderstood functionalities in IT. Everyone takes it for granted unless it is missing or badly implemented. The other day I was asked how can I learn search, with Solr? There are manyways, although I’ve done what I can to help others learn enterprise search. Here are three resources: Pluralsight Online Solr Training I created two trainings that teach you what you need to know to get started with Solr and create a search API with Solr and SolrNet (oriented towards Microsoft-centric technologies, i.e. C#). Best part is that it is only $29 a month to get a subscription to Pluralsight and you can learn about many other topics that are relevant for your career. Getting Started with Enterprise Search Using Apache Solr Implementing Search in .NET Applications Cloudera Search Instructor-led Training If you prefer to take an instructor-led training, Cloudera has a great training, with amazing instructors to teach you Solr. If you were not aware, Cloudera Search is actually Solr but running on top of a Hadoop cluster. So hello Big Data! Cloudera Search Training SyncFusion Apache Solr and SolrNet Book I published a book on Solr for SyncFusion. It is part of […]

The Power of Experience and Maturity in Programming (and Life)

17 Apr 2018 by Xavier in General 0 comments
It was a Friday night like any other. At least that is what I thought, until a small accident occurred that made me think hard about the power of experience in life and and my career as a computer programmer. So, what happened? Over the course of the week, I had already clocked somewhere between 60 to 70 hours of work between my day job, keeping the wheels turning in my service application software, over-seeing my small support center, and working on my Pluralsight authoring. My wife was probably twice as tired as I was, having cared for our two young kids, which is unimaginably more demanding than sitting or standing in front of a keyboard, several monitors, lots of emails, and abundant CPU power. In any case, I was more than ready to spend some quality time with my wife, talking about the same things as we always do on Fridays. Being an entrepreneur—albeit a small one like me—means working a lot, so we barely see each other during the week. I usually leave home at 5:40am to my day job, work all day, then do the one hour drive back at 5pm to show up for bedtime, see […]
