Fuad Efendi commented on LUCENE-1995:
-------------------------------------
But who did the bug? Joshua writes, it's him :) - based on other's famous
findings and books...
===
" it just contains a few lines of code that calculates a
double value from two document fields and then stores that value in one of
these dynamic fields"
And problem happens when he indexes document number 15,000,000...
- I am guessing he is indexing "double"... ((type=tdouble, indexed=t,
stored=f)... Why do we ever need to index multi-valued field "double"?
Cardinality is the highest possible... I don't know Lucene internals; I am
thinking that (double, docID) will occupy 12 bytes, and with multivalued (or
dynamic) field we may need a lot of RAM for 15 mlns docs... especially if we
are trying to put into buskets some objects using hash of "double"...
