Each record has the same three parts: the problem, the approach, and the conclusion. Filter by subject. Open a title for the full record.
7 records
Search a citizen can use: a polling place, a beneficiary record, found in hundreds of millions of rows.
At that size the interface is the product. If the person cannot tell they found the right row, the index does not matter.
A books-and-journals search that let people explore by concepts, built in 2018 from phrases and similarity, not from a vector database.
A concept a person can read beats a similarity score they cannot. The same idea shows up now in hybrid retrieval: use the dense signal where meaning is fuzzy, and keep a precise handle where it is not.
Product search, autosuggest, filters, and per-field similarity for an omnichannel retailer: web, marketplace, and stores.
Omnichannel is a relevance problem before it is a channel problem. The field knows what 'close' means. The ranker has to follow.
From millions of candidates that share an organisation's name and address, return the single best record.
Ask what the caller will do with the answer. If they will act on one row, tuning a list of ten is a different job, and it can look like progress while the decision gets worse.
A production move from self-managed Apache Solr to managed OpenSearch, checked by whether the top results still agreed.
Finish the migration when the results agree, not when the dashboard is green. The same habit applies to hybrid retrieval: measure the blend, do not assume the new signal is kinder.
Leading a search engineering group while staying close enough to the system to tell a relevance question from an operations question.
Your output becomes the output of the team. That is also how you keep a search platform honest: more than one person can explain why the top result is the top result.
Your output is no longer your outputYour First 90 Days as a New Engineering Manager
A hands-on reading of Luxir, a new hybrid search engine, run from a Mac or Windows laptop without compiling C++.
Treat a new engine as a thing you can run. Text, vectors, facets, and geo in one request is the idea. The laptop guide is there so the idea is not trapped in a slide.
