Give empty results and transport failures different screens
Separate a successful empty quantization search from HTTP errors and a missing response, while retaining the submitted question and making retries deliberate.
Define response classes
A blank results area cannot explain what happened to a search. In the proposed LocalLLaMA notebook, distinguish a request still in progress, a successful response with records, a successful response with an empty data array, an HTTP error, and a transport attempt from which no usable response arrived. These are different observations. In particular, an empty success does not prove that the archive contains no relevant discussion, while a lost response does not reveal whether the server completed the request. Keep those interpretations out of the visual shortcut no results.
Use the HTTP status and validated response shape together. A 200 response containing data: [] is a successful empty retrieval. HTTP 400, 401, 402, 429 and 502 are error responses, not alternative kinds of successful empty data. A network exception may provide no HTTP status at all. Do not infer from an error alone whether a request reached every backend stage. Keep the submitted parameters and an application request identifier with each outcome so a later response can be attached to the correct search.
Write empty-state actions
Use restrained copy such as No records were returned for this request. Show the submitted q=quantization and subreddit=LocalLLaMA nearby, along with any active date or score restriction. Offer a deliberate way to edit one condition and submit again. Do not replace the empty response with invented popular discussions or automatically broaden the query while leaving the old label in place. If a reader removes a filter, the next result belongs to that changed request and should begin a new page-1 sequence.
Explain a relevant constraint without pretending to diagnose the absence. For quantization memory, all analyzed terms must match within a matching title or text field; a split across the two fields is insufficient. That is one possible consideration, not proof of why this response was empty. Preserve the billing distinction: successful empty retrieval still costs one credit. An empty deep page can also have an unknown total. Do not turn it into a claim of zero matches throughout the archive or a reason to keep requesting pages indefinitely.
Write failure-state actions
Map the error to the person who can act on it. HTTP 400 calls for checking the actual input, such as an unsupported parameter or a date that is not YYYY-MM-DD. HTTP 401 concerns the service API key, and 402 the service account's available credits; neither establishes that the reader's own application login has expired. The operator may need to correct the backend credential or review the balance. Avoid asking the reader to paste a service key into a public search screen.
For 429, respect Retry-After and reduce repeated submissions. For 502, preserve the query and offer an intentional retry when appropriate; reserved-credit refunds may be pending reconciliation. A missing response needs different wording: the outcome is not known, including whether a successful request was charged. Invalid requests rejected before reservation are not charged, but a connection failure does not prove that rejection occurred. The uncharged /v1/status endpoint reports a static service disclosure and HTTP responsiveness; it cannot settle the lost request or verify search health.
Test navigation continuity
Continuity also involves preserving the user's input state. Plan local fixtures for a valid empty response, an HTTP error and a network exception before a response is available. Use explicitly synthetic material; these fixtures would test your interface, not establish archive availability. Check that each produces distinct copy and leaves the submitted query accessible. Add a case where the reader changes the form while a request is pending: the old outcome must not appear as an answer to the new wording.
For a failed next page, retain the already loaded records and distinguish their completed state from the failed continuation. Let the reader retry that page or return to the form without silently issuing another request. Ignoring a late response in the interface does not guarantee cancellation of server work. Record which transitions your application actually tests and which remain proposed. The aim is a screen that tells the reader what is known and offers a useful next action, rather than a reassuring message unsupported by the response.
