The Open Crawler lets users crawl web content and index it into Elasticsearch from wherever they like. Learn about it & how to use it here.

Background

What has changed?

How does the Open Crawler compare to the Elastic Crawler?

Requests (n)

So why is the Open Crawler so much faster?

1. The Open Crawler makes significantly fewer indexing requests.

2. Elastic Crawler also performs many search requests, further slowing down performance

3. Open Crawler is simply doing less with crawl results

How do I use the Open Crawler?

1. Build the Docker image and run it

2. Configure the crawler

3. Validate the domain

4. Crawl!

5. Check the content

Learn how to manage connectors and use the Connector API to ingest data from MongoDB or other sources into Elasticsearch Serverless.

Prerequisites

Elasticsearch Serverless

Our product catalog

Create a MongoDB connector

Triggering an on-demand sync

Keeping your ES index in sync with source

Sync Rules - Index only what you want

Generate vector embeddings at ingest time

Monitoring your connectors

Tips on automation

Next steps

Appendix

Spin up MongoDB instance with Docker

The Elastic Connector API is used to fully manage Elastic connectors directly from your command-line interface. This is especially useful for specific workflows, as it can automate connector management, monitoring and testing, removing the need to go back and forth between a terminal and the Kibana UI.

Learn about full sync and incremental sync for connectors. Discover how incremental sync can boost the performance of Elastic connectors.

Elastic Connectors overview

Connectors content synchronization jobs

1. Full syncs

2. Incremental syncs

Potential optimizations for incremental sync

Fetch fewer documents from 3rd-party systems

Skip download of content of files that haven't changed since previous sync

Skip ingestion of non-modified documents into Elasticsearch

Measuring incremental sync performance

Performance tests

Setup #1 - Google Drive Connector

Setup #2: GitHub connector

Key takeaways

Summary

Elastic Connectors are a type of Elastic integrations that sync data from an original data source to an Elasticsearch index. Connectors enable you to create searchable, read-only replicas of your data sources.

Learn through an example how to leverage the Elastic Web Crawler to crawl a website, ingest its content & prepare the data for search.

What is the Elastic Web Crawler

Website discovery & web crawler creation

A first crawl

Define crawl rules

Enrich the data extracted by the web crawler

Extract data from custom field

Ingest pipeline to transform data

Enable semantic search with ML Inference pipeline

Test search query

Preparing the web crawler for production deployment

Scheduling

Protected website

Conclusion

The Elastic web crawler is an out-of-the-box tool that enables users to crawl a website and ingest its content into Elasticsearch.

What is the Elastic Web Crawler?

The Elastic web crawler begins each crawl by visiting the entry point URLs. From there, the crawler fetches the content from this webpage and extracts it. The HTML document is transformed into a search document and indexed. Then it follows any links to which that page points to, respecting the rules defined by the user. The new URLs are visited using the same methodology until the crawler has indexed the accessible web pages.

Introducing the Data Extraction Service

What’s next?

What’s the long-term dream?

It is a dedicated, standalone server that is capable of taking your binary documents as input (via a REST API) and responding with their plain-text contents, as well as some minimal metadata.

Learn how to create custom connectors for Elasticsearch to simplify your data ingestion process.

Framework to create custom connectors

What you need to know before you use connectors framework

The framework is written in async-python

Why did we choose async python?

Any other pre-requisites?

Using connectors framework to create a custom connector

Outline of steps

What you need to know before writing your custom connector

What you need to know about connectors protocol

Where custom connectors are hosted

Example: Google Drive connector using connectors framework

How we approached writing the official Elasticsearch Google Drive connector

Start by implementing the methods expected by the BaseDataSource class

The first consideration is: How to “talk” to Google Drive to get data?

The next concern is the connector authentication

Next, let’s implement a simple ping method

Async iterator to return files from google drive for content extraction

Let’s run the connector!
