Apache Solr, Elastic Stack & OpenSearch Experts
From Fortune 100 to Startups
Our Elasticsearch, Apache Solr & OpenSearch expertise is as good as there is in the industry. That is how we have built a client list ranging from Fortune 100 organizations down to innovative startups and everything in between.
In fact, many of our customers have reengaged us a second or third time. Sematext provides comprehensive service to each client: from consulting and development support, production support to proprietary solutions and Solr, Elasticsearch & OpenSearch training.
We are agile and globally distributed; our team is spread over several time zones and continents, and includes book authors, conference speakers, and expert open-source developers.
We chose Solr/Lucene as our search platform for shortcovers.com. We had a very short timeline to put together a production level solution; reaching out to Sematext for help was a right call. The team at Sematext is amongst the best professionals we’ve worked with. Fast, responsive, to the point, with the depth of knowledge that is required to create a sophisticated search solution in a short period of time.

We’ve had an incredibly positive experience with Sematext. From the team’s initial responsiveness to their expertise in helping us migrate from Solr to SolrCloud in just a few short weeks, the team has been invaluable to us. We had the chance to work with Radu and would work with him again in a heartbeat.
