Shai Erera commented on LUCENE-2806:
------------------------------------
Ok -- I looked at 3x source code, but I see you marked the issue as 3.0.3 and
that TermScorer's lines are different between 3x and 3.0.3. The offending line
looks like:
{code}
return norms == null ? raw : raw * SIM_NORM_DECODER[norms[doc] & 0xFF]; //
normalize for field
{code}
And it can be thrown by either invalid access to the 'norms' array, or the
SIM_NORM_DECODER array. Are you using a custom Similarity maybe? I think it's
less likely that the invalid access is caused from the 'norms' array, as it is
allocated in the size of the index (one norm per document).
Are you able to rebuild the index? If so, I'd suggest to rebuild it and add all
content as ANALYZED_NO_NORMS to disable norms. If the AIOOBE still happens,
then we know it's from the SIM_NORM_DECODER, otherwise it's from the norms[]
array.
Also, does it happen in other queries too? Maybe to remove some noise, remove
the *field:word** part and only keep the type:document part? Trying to minimize
the query down to few select terms to ease on the debugging.
Can you perhaps post the index here?
