Facebook - max number of parameters in “IN” clause?

Question

In Facebook query language(FQL), you can specify an IN clause, like:

SELECT uid1, uid2 FROM friend WHERE uid1 IN (1000, 1001, 1002)

Does anyone know what's the maximum number of parameters you can pass into IN?

Answer 1

I think the maximum result set size is 5000

Answer 2

It may seem like an odd number (so perhaps I miss counted, but it's close ~1), but I can not seem to query more than 73 IN items. This is my query:

SELECT object_id, metric, value
FROM insights
WHERE object_id IN ( ~73 PAGE IDS HERE~ )
AND metric='page_fans'
AND end_time=end_time_date('2011-06-04')
AND period=period('lifetime')

This is using the JavaSCript FB.api() call.
