I'm getting the error
ValueError: Keys must increase: '\x00\x00\x0b\xc4\x00\x01' .. '\x00\x00\x0b\xc4\x00\x01'
at the line
writer.commit()
Where writer is an index.writer. I am adding 10K files to the index, and for performance, I commit every 100 files. This error only occurs at the 21st commit (20999 files).
The stack ends at add_all in whoosh...\filetables.py
