Subject [jira] [Commented] (LUCENE-3037) TestFSTs.testRealTerms produces a corrupt index
Date Tue, 19 Apr 2011 18:02:05 GMT


Dawid Weiss commented on LUCENE-3037:

I don't know how applicable is this, but floor(log(n)/log(m)) = p can be transformed into
a simple equation: find first 'p' for which n <= m^p is true. Assuming m^p grows quickly,
this can be computed in a tight loop, quite fast and with an exact result.
