I am attempting to formulate a query that finds song length by a specific artist. I am getting incorrect results for both fields. There are 54 hits with neither of the criteria. Also, I am getting hits for 2 0r 3-second sound samples.
One small improvement could be if you want to have also results near the given length is to use the qdur (quantized duration) parameter which expects duration / 2000 (half the duration in seconds).
This will give you results near the queried duration (I’m not entirely sure, but I think +/- 2 seconds). So instead of dur:184000 you could use qdur:92 which gives more results:
