Build Nostr Search Around Records, Not Just Replies

A community asks which release fixed a problem. The information exists in announcements, discussions and long-form posts, but the user has to recognise the right author, find the relevant version and check whether a later post superseded it. A fluent summary alone does not resolve those questions.

A useful Nostr search product returns the underlying records as well as any summary. The reader should be able to inspect the author, event identity, time, applicable version and referenced artifacts without relying on the language model's retelling.

That is an attractive evaluation direction for the Nostr, Nosternity and ECAI components. It is not a claim that the latest search relay has passed interoperability or relevance tests. The complete current search implementation was not retrievable for this review.

NIP-50 adds a human-readable search field to relay queries. It leaves the ranking algorithm to the implementation and recommends applying the result limit after ranking. Support for that interface is therefore different from good search results.

An evaluation should test discovery of search support, interaction with structured filters and ranking on a representative collection. Check that a query restricted to the intended authors or event kinds stays restricted. Do not label a relay NIP-50-compatible solely because an HTTP endpoint accepts a query string.

Compare retrieved event identities with a small, independently labelled set. Record which relevant events are absent, which irrelevant events appear and how current-version rules affect the answer. A different ranking method is valuable only when it helps the application's actual questions.

The existing Nosternity implementation reference distinguishes relay delivery from retention of selected signed events. Its historical integration review also identifies gaps between local acceptance, queued work and confirmed storage. Those findings require a fresh source and recovery check before making a durability promise.

An archive and a current-view search index have different purposes. Keeping an old event can preserve history; presenting it as the current answer can mislead a reader. Define how replacements, deletions, expiry, duplicates and moderation affect the user-facing view before admitting real community data.

The same policy should apply to a context API consumed by a model. Removing an item from search while continuing to send its text to the model does not provide a consistent retrieval boundary. These are proposed acceptance cases, not a report that every path already implements them.

Begin with an event list that is useful without a model. Show identifiers, author information and enough context for a person to decide what to open. Then evaluate an optional summary generated from that bounded result set.

Require the summary to identify its supporting records. When no suitable record is found, the interface should say so instead of supplying an unattributed answer. Retrieved text is untrusted input; an instruction inside a post must not grant access to secrets or turn on an execution tool.

Publicly signed content is not automatically true. A signature helps establish which key signed the record, while source selection, context and evaluation remain separate responsibilities. Likewise, geometric or deterministic index operations do not prove that a generated explanation is correct.

Choose a public release-announcement collection or a consented support archive. Create a small question set with known relevant records, including changed answers and questions that should remain unanswered. Compare raw filtering, a straightforward text-search baseline and the proposed indexed retrieval.

Measure useful-result rate, source-link correctness, query latency, ingestion lag and recovery after restart. Add malformed events and interrupted writes. Keep retention and chain costs separate from query costs so the operator can see what each service decision costs.

The first buyer is an application developer who needs an inspectable knowledge feature, not someone seeking a universal truth engine. Keep signing, paid retention and language-model access optional within the evaluation until each has a concrete purpose.

This is a product-evaluation blueprint grounded in the linked protocol and dated component guides. It does not announce completed NIP-50 support in the latest checkout. The 7 October review is a historical baseline, not evidence that later additions are absent or broken.

Use the Nostr integration guide to establish the event path and the search-evidence guide to examine retrieval claims. Make the records useful before asking a model to speak for them.
