Karl Wettin updated LUCENE-550:
-------------------------------
Attachment: LUCENE-550_20070808_no_core_changes.txt
Added support for payloads
Reintroduced InstantiatedIndexWriter (no locks!)
Reintroduced TestIndicesEquals
Introduced build.xml
Introduced pom.xml (this file is missing java 1.5 setting)
Added some silly javadocs
It also hit me that I could have a HashMap<Term, Integer> parallell to the
List<Term> orderdTerms. The latter is currently beeing binarysearched in
TermEnum, and a HashMap would make it much faster, especially as the index
grows. Might speed things up alot.
> InstantiatedIndex - faster but memory consuming index

> An non file centrinc all in memory index. Consumes some 2x the memory of a
> RAMDirectory (in a term satured index) but is between 3x-60x faster depending
> on application and how one counts. Average query is about 8x faster.
> IndexWriter and IndexModifier have been realized in InterfaceIndexWriter and
> InterfaceIndexModifier.
> InstantiatedIndex is wrapped in a new top layer index facade (class Index)
> that comes with factory methods for writers, readers and searchers for unison
> index handeling. There are decorators with notification handling that can be
> used for automatically syncronizing searchers on updates, et.c.
> Index also comes with FS/RAMDirectory implementation.
