Our summary
PostgreSQL stores organized records and can filter them using exact conditions. jevql adds questions about meaning without making the database itself perform every model call. A separate tool collects selected records, asks Jev about them, and attaches the answers for later filtering or sorting.
The guide describes collecting records, arranging their fields consistently, and checking groups while saving reusable answers. Before sending anything, a preview shows the database request, record and group counts, approximate text volume, and estimated cost. This makes unexpectedly large jobs easier to spot.
The first version supports only some read-only database requests and stops when important details are unclear or change. Sorting by meaning may still require checking every candidate record. Set limits on records and text, and remember that selected database contents go to an outside service.
Key takeaways
- Apply exact database filters before asking about meaning.
- Limit records and text so oversized jobs stop.
- Inspect unsupported requests instead of accepting a guessed interpretation.
