Search Engines with OpenSearch
Like Duolingo, but for Search Engines with OpenSearch. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
24 levels across 4 sections, about 48 minutes end to end, roughly 10 days at five minutes a day. It moves through Getting Results Fast, Organizing Your Data, Judging and Summarizing, and The Engine Under the Hood. It starts from scratch.

Key ideas in Search Engines with OpenSearch
- Indices act as the primary container for organizing searchable data
- An index should group documents with the same structure and purpose
- Books and Locations have different fields and should live in separate indices
- OpenSearch uses standard HTTP verbs to manage data
- The API allows any tool that speaks 'web' to communicate with the engine
- Specific methods correspond to CRUD (Create, Read, Update, Delete) operations
- Understanding how to organize data into indices
- Mapping REST API methods to their actions in OpenSearch
- OpenSearch calculates a score to find the 'best' matches, not just perfect ones
- Search engines are designed to handle typos or related terms through fuzzy matching
- Relevance is what separates a search engine from a simple database filter
- The 'hits' object contains the metadata and the actual results of a search
- Each result inside 'hits' includes a '_score' indicating how well it matched
- Searching 'all fields' often returns noisy, irrelevant results
- Distinguishing between exact matching and relevance-based searching
- Targeting a specific field (like 'author') limits the search scope to that data point
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Search Engines with OpenSearch the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
