Elasticsearch for Product Searches

Make Product Search Better

Rating 

Our Elasticsearch training classes have a 4.67/5 rating based on 15 reviews

This 2-hour online course focuses on E-commerce or similar product search use-cases (e.g. searching for phones, books, people, blog posts). Because relevancy is important for product search: Elasticsearch shouldn’t return “phone accessories” on a query for “phone”. Other challenges might come up as well, for example dealing with relational data, providing autocomplete or did-you-mean functionality. This course provides solutions to these challenges. Radu Gheorghe, a seasoned Elasticsearch instructor, and consultant from Sematext, author of “Elasticsearch in Action”, and frequent conference speaker will be your trainer.

This Elasticsearch online course is designed for anyone who:

  • Has a basic understanding of Elasticsearch’s core concepts (documents, shards, basic queries)
  • Is looking to implement product search.

What attendees say

Sematext was an ideal training partner for Parse.ly. We had just recently adopted Elasticsearch on a new project, and they gave us two days of solid training that was tailored to our team’s needs. The material was built atop strong foundations and moved quickly into advanced areas around querying, Lucene internals, and cluster performance. It was clear that it was all informed by real-world experience operating these systems at scale.

Relevancy tuning
  • Using ngrams and shingles to tolerate typos, while boosting relevant matches
  • How is relevancy score calculated?
  • Searching across fields to detect user intent
  • Balance precision and recall by using different variants of the same field

  • Lab
    • Using ngrams and shingles to boost more exact matches
    • Boosting documents based on recency
    • Dealing with stopwords efficiently
Relational data in Elasticsearch
  • Arrays and objects: fastest way to deal with one-to-one relations
  • Nested documents: quick searches for low-velocity data
  • Parent-child relationships: fastest way to update

  • Lab
    • Searching across a relationship between two documents
    • Showing both sides of the relationship in the results
Suggesters

  • Filter autocomplete results with the context suggester
  • Lab
    • Implementing did-you-mean functionality

  • Term vectors: paying with storage to get the best of both worlds
  • Lab
    • Add highlighting for query results
 

Main Topics

  • Balance precision and recall through analysis tweaks
  • Using DisMax and Function Score to make relevant documents rank higher
