Overview of this book

Even structured data is useless if it can’t help you to take strategic decisions and improve existing system. If you love to play with data, or your job requires you to process custom log formats, design a scalable analysis system, and manage logs to do real-time data analysis, this book is your one-stop solution. By combining the massively popular Elasticsearch, Logstash, Beats, and Kibana, elastic.co has advanced the end-to-end stack that delivers actionable insights in real time from almost any type of structured or unstructured data source. If your job requires you to process custom log formats, design a scalable analysis system, explore a variety of data, and manage logs, this book is your one-stop solution. You will learn how to create real-time dashboards and how to manage the life cycle of logs in detail through real-life scenarios. This book brushes up your basic knowledge on implementing the Elastic Stack and then dives deeper into complex and advanced implementations of the Elastic Stack. We’ll help you to solve data analytics challenges using the Elastic Stack and provide practical steps on centralized logging and real-time analytics with the Elastic Stack in production. You will get to grip with advanced techniques for log analysis and visualization. Newly announced features such as Beats and X-Pack are also covered in detail with examples.

Querying and Searching data


The search box is used to perform various types of queries that fetch the matching documents. Upon searching, the whole Discover page along with its components gets automatically refreshed. Kibana uses the underlying powerful capabilities of Lucene query syntax using the data that is queried. As Kibana utilizes the functionality of the underlying Elasticsearch, Lucene queries provide the ability to perform various types of searches ranging from simple to complex queries.

Lucene queries provide a number of ways to search data. Let's look at these one by one.

Full-text searches

This is used to search for a term within the complete text. The different ways to search for full-text are shown as follows:

  • Search for the single term:

    Example: To search for a phrase, type elasticsearch kibana in the search bar.

  • Search for a phrase (group of words):

    Example: To search for a single term, type kibana in the search bar.

    Note

    By default, phrases use, OR Boolean operator to search for...
