Modules
Introduction to Elasticsearch
• Learn about Elasticsearch and Lucene, the components of Elasticsearch, and how to index documents using the REST and Bulk APIs
• Hands-on Lab : Index a dataset, then search the data using
Elasticsearch.
The Search API
• Learn how to write and submit queries, how the scoring and relevance of
matching documents is calculated, and how to boost relevance at query time
• Hands-on Lab: Write various queries that search documents
using Search API queries like match, range and bool
Text Analysis
• We walk through the details of how full text is analyzed and indexed inElasticsearch, including a discussion of the various analyzers and filters and how to configure them
• Hands-on Lab: Perform the steps for configuring text analysis
in Elasticsearch; use the Analyze API to see how the built-in analyzers work; define custom analyzers by configuring character filters, tokenizesand token filter
Mappings
• Learn how Elasticsearch mappings are used to define how your documentsand fields are stored and indexed, including how to
define multi-fields, custom analyzers, and index templates
• Handson Lab: Define a custom mapping for a new index; use
an index template to customize a mapping
More Search Features
• Learn how Elasticsearch mappings are used to define how your documentsand fields are stored and indexed, including how to define multi-fields, custom analyzers, and index templates
• Hands-on Lab : See how a terms query works in Elasticsearch;
write multi_match and more_like_this queries; see how the fuzziness parameter works and how to highlight search terms
The Distributed Model
• Understand how Elasticsearch scales and distributes data across a cluster, including a discussion on shards, how to startup a multi-node cluster, and how data replication works in
Elasticsearch
• Hands-on Lab : Startup a multi-node cluster and see how
documents indexed into Elasticsearch are distributed across shards in the cluster
Working with Search Results
• Learn how to perform common tasks when working with search results like sorting, pagination, and performing scroll searches
• Handson Lab : Run queries that involve controlling the results of searches using relevance boosting,sorting,and pagination
Suggesters
• Learn how to provide autocomplete suggestions for users, as
well as "did youmean" suggestions when users misspell terms in
their queries
• Handson Lab: Implement a "did you mean" and autocomplete
solution using suggesters
Aggregations
• An introduction to aggregations, including a discussion the different types of aggregations, how to perform metric and bucket
aggregations, and details on
how to use some of the more common aggregations
• Handson Lab: Perform various metrics and bucket
aggregationson the products index and also on some stock
market trade data
More Aggregations
• We take a deeper dive into aggregations and discuss scope, using post_filter for faceting, creating histograms, finding the top hits of an aggregation, and an example of the significant terms
aggregation
• Handson Lab : Perform various advanced bucket and metrics
aggregations on the stocks index
