Yes, in fact I tried, but it goes straight to [dead] after several minutes. I suppose it's some sort of automatic filtering with "false negatives" based on who knows what parameters.
Shameless plug: made a searcher for this (and any other HN's) thread - it runs locally in-browser by loading all top-level comments to in-browser SQLite, lets you run regular SQL and also full-text search (FTS4) to filter results any way needed. Then you can save/load db as a regular SQLite file. https://mstrahov.github.io/hnsql/?32306920 Hope it's useful, thank you!
New users' posts to "Show HN" seem to be marked as possible spam sometimes and appear as [dead]. I guess we shouldn't be discouraged if it happens and just try again.
