elasticsearch-dump. Neat open source utility by TaskRabbit for importing and exporting data in bulk from Elasticsearch. It can copy data from one Elasticsearch cluster directly to another or to an intermediary file, making it a swiss-army knife for migrating data around. I successfully used the “docker run” incantation to execute it without needing to worry about having the correct version of Node.js installed. # 9th April 2018, 10:10 pm

Building a Full-Text Search App Using Docker and Elasticsearch. Deep, comprehensive tutorial from Patrick Triest showing how to use docker-compose to run three containers (Node API, nginx static content, elasticsearch) and then use that to build a neat Vue.js web search UI against 100 books from Project Gutenberg. # 1st February 2018, 3:41 pm

We are actively developing cross datacenter replication (internally we are calling it “cross cluster replication” so you will likely see it referred to this in the future but of course this is subject to change). I can not give a timeframe, but it is one of the top features on the Elasticsearch roadmap.

gillyb/sensitive: A native desktop version of the kibana sense plugin. I love using the Sense UI for developing against Elasticsearch, but it’s infuriatingly hard to obtain these days. You can install it as a Kibana plugin but I work with multiple Elasticsearch instances and I don’t want to have to get it installed on all of them. Until recently I was using a Chrome extension for it, but that’s now been disabled as containing malware and removed from the Chrome extension store. I’ve now switched to Sensitive, which packages Sense up as a native OS X application using Electron. # 4th November 2017, 7:35 pm

elasticsearch: Percolator. Another fascinating elasticsearch feature: Percolator lets you register searches with your elasticsearch cluster, then pass in a document and have the matching query IDs returned. It’s an upside down search engine. I’m sure there are some very neat things you could build with this, I just haven’t figured out what they are just yet. # 8th February 2011, 11:16 pm

ElasticSearch memcached module. Fascinating idea: the ElasticSearch search server provides an optional memcached protocol plugin for added performance which maps simple HTTP to memcached. GET is mapped to memcached get commands, POST is mapped to set commands. This means you can use any memcached client to communicate with the search server. # 15th May 2010, 10:17 am

Search Engine Time Machine. Detailed explanation of how ElasticSearch provides high availability, through clever sharding and replication strategies and configurable gateways for long-term persistent storage. # 17th February 2010, 10:32 pm

ElasticSearch: Your Data, Your Search. A neat example of how ElasticSearch’s schemaless indexes and native JSON support make it ridiculously easy to index different types of data and run queries across them. # 12th February 2010, 3:22 pm

Elastic Search (via) Solr has competition! Like Solr, Elastic Search provides a RESTful JSON HTTP interface to Lucene. The focus here is on distribution, auto-sharding and high availability. It’s even easier to get started with than Solr, partly due to the focus on providing a schema-less document store, but it’s currently missing out on a bunch of useful Solr features (a web interface and faceting are the two that stand out). The high availability features look particularly interesting. UPDATE: I was incorrect, basic faceted queries are already supported. # 11th February 2010, 6:33 pm
