[CWB] Problems with CQPweb frequency list permissions

[Stephanie Evert]

> What am I missing?

Frequency list privileges are used for compiling frequency lists for subcorpora of the specified size.  They don't apply to other cached databases, such as collocation tables, frequency breakdown, etc.

Apparently the latter limit can only be changed for each individual user via the user admin page. The setting is at the very bottom of the page, just a little below the point where a sane person has given up on scrolling down.

It is set to 1,000,000 rows for the users in question, and 10,000,000 rows for cqpwebadmin, which seems to explain the behaviour you're seeing.

> This is bizarre because (a) a breakdown of 300,000 matches should have less than 1 mio. instances and (b) the user has been explicitly granted the right to build frequency lists of up to 1 billion tokens.

The 1,000,000 limit should allow you to do a frequency breakdown of 300,000 matches, but for a collocation database the # of matches is multiplied by a (default) cost factor of 4, giving an effective table size of 1,200,000 > 1,000,000 rows.
