Introduction to Apache Solr 8

Whether you’re handling big data, building cloud-based services, or developing e-commerce web applications, its vital to have a fast, reliable search solution. Introduction to Apache Solr 8 is a quick start guide if you are interested in learning how to leverage a search engine that is optimized to search large volumes of text-centric data. This course will have you successfully using Solr in no time! Most of the sections use coding activities to help master the material. All code snippets and commands are available on Github, so you can try them for yourself. Our goal for each example was that it be easy to use but cover the chapter topic thoroughly. In addition, after almost all video lectures you will have the chance to test your knowledge by answering the quizzes. Learn Apache Solr 8 Overview: Understanding Search EnginesUnderstanding search engines and the issues they addressHow Solr fits in the context of search enginesGet a good sense of what types of data and use cases Solr supports. Typical scenarios for SolrYoull learn about the kinds of problems you can solve with Solr and gain an overview of its key features. Getting Started with SolrHow to install and run Solr on your local workstation. Introduction to Solrs core configuration files. What is a Solr Core/Collection and how to create it. Demonstrate how to index and query a set of example documents that ship with Solr. Introduction to Solrs query form and learn the basic components of a Solr query. How to construct queries containing a main query parameter q as well as an optional filter fq. You saw how to control which fields are returned using the fl parameter and how to control the ordering of results using sort.A brief tour of Solrs web-based administration console. Designing our first Solr ApplicationIntroduce a fictitious web application for finding tweets. What a document is in Solr and what characteristics it has. Well get an overview of how Solr processes documents, to build the index. Designing the SchemaUnderstand what is and when to use the Schemaless modeHow to manage many of the elements of your schema via The Schema API using HTTP. Learn about key design considerations for search applications. Discussed considerations about document granularity. Learn how to determine if a field should be indexed, stored, or both. Learn how to determine if a field should use docValues. Use multivalued fields for more complex document structures. Understand how dynamic fields are useful for supporting documents with many fields and documents coming from diverse sources. Learn how to use Solrs copyField directive in order to populate a catch-all text search field. How to work with structured data using Solrs support for strings, dates, and numeric field types. Manipulating the IndexGet an overview of common request types supported by the update handler. Beyond adding new documents, well learn how to update existing documents using Solrs atomic update support. We’ll explain how to guard against concurrent updates using optimistic concurrency control with the special version field. Well see that after documents are processed, they need to be committed using either hard commits or soft commits for NRT search. We also learned how Solr processes query requests using a read-only view of the index with a component called a searcher. Explore how to model documents containing other documents using nested documents feature. Understand which types of changes require data reindexing, and how to manage the process of reindexing. Learn about segment merging and that its a good idea to avoid optimizing your index or changing segment-merge settings until you have a better understanding of your indexing throughput requirements. Text AnalysisIntroduction to text analysis and why is an important part of the search process as it removes the linguistic variations between indexed text and queries. Learn how to define field types to do basic text analysis. Learn why field types for unstructured text-based fields are normally composed of two separate but compatible analyzers for indexing and query processing. Understand why each analyzer is made up of a tokenizer and chain of token filters. Test our simple analysis solution using Solrs Analysis form and see how documents pass through StandardTokenizer and a chain of simple filters to remove stop words and lowercase terms. SearchingUncovering Solrs capabilities through its numerous and highly configurable request handlers pipeline. We discussed how Solr handles queries and filters to get a good understanding of how user queries and filters work: what the difference is, how they interact, and how they ultimately affect the performance and quality of your search requests. Describes the syntax and features supported by the main query parser, The Standard Query Parser, included with Solr and describes some other parsers that may be useful for particular situations. How to use facets for discovery, analytics, and filtering of search resultsShow top values in any field for matching documents via field
