Elasticsearch has a vast number of ways to query the data in your index. How you query your data is very much dependent upon where it is being used, so in this post we’re going to talk about how we use it in our instructor search application. Continue reading

    Elasticsearch Series: Rebuilding Indices with No Downtime

    March 2, 2016 engineering
    This is the first entry in a series on Elasticsearch and how we use it in Zumba’s applications. Many of Zumba’s applications have some form of search. In the beginning, many of these were implemented via querying MySQL. As you can imagine, this doesn’t scale very well. On top of that, certain types of queries, such as geo location, are difficult to accomplish (read: we have to do math). Continue reading
