Tsuyoshi Ito commented on CLEREZZA-388:
---------------------------------------
I am not sure: Probably because of inline functions within functions.
Additionally inline functions in scala makes it difficult for me to
understand/read the code of CRIS (Alle functions are defined and executed
within in the constructor)
new IndexSearcher(index, true) opens at least one new file (and it will never
be closed) => after a few searches within 300'000 triples a "too many files
open" exception occurs. I never had this problems bevor with tdb (constantly
about 600 files open).
IMO if IndexSearcher and IndexWriter would be available once per lucene
directory (as service?) I think we could reduce the number of files resp. keep
it constant.
