The work

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

04Return one record, not a list

From millions of candidates that share an organisation's name and address, return the single best record.

The conclusion

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.

05A move that kept the answers

A production move from self-managed Apache Solr to managed OpenSearch, checked by whether the top results still agreed.

The conclusion

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.
