Hi. We had some empty fields in our records and they caused an error which I tracked down in search_engine.search_pattern. The problem is that when searching with an empty search string, search_pattern returns an infinite bitset. And Python is unable to iterate over such a bitset.
In [1]: from invenio.intbitset import intbitset In [2]: for i in intbitset(trailing_bits=1): ...: print i ...: ...: --------------------------------------------------------------------------- OverflowError Traceback (most recent call last) /home/bthiell/src/invenio/<ipython console> /usr/lib64/python2.4/site-packages/invenio/intbitset.so in lib.intbitset.intbitset.__iter__ (intbitset.c:5172)() OverflowError: It's impossible to iterate over an infinite set. This caused an error for us in search_engine_summarizer.get_coauthors when we encountered an empty author field. We cleaned our record but the problem should also be fixed in the code.
