How often does Hacker News discuss prompt injection, month by month?
One query, one row per month, a real count in each — not ten links.
Methodology
The search line `"prompt injection" source:hackernews` compiles to index-engaging predicates — POST /v1/scry/compile shows the exact WHERE — and scry_lex('…') embeds the same line inside SQL, so the monthly series is a GROUP BY away. A ranked engine has no count at all; every how-common and growing-or-shrinking question is this shape.

What does a Scry search line compile to?
Readable, editable, index-engaging SQL — POST /v1/scry/compile returns it, scry_lex('<line>') embeds it in any statement, and the search panel's 'as SQL' door shows it.
