Challenges: Analyzers
Explore how to create and implement custom analyzers in Elasticsearch. Learn to generate prefixes, handle punctuation, customize standard analyzers, and preprocess complex text for better searchability and data analysis.
Challenge 1: Prefix generator analyzer
Define a custom analyzer called the prefix_generator_analyzer in an index called challenge_1. The analyzer should produce the prefixes for each word in the input text. Specifically, the analyzer should be able to process the text "hello world" and generate the prefixes of the words "hello" and "world", which are:
