[jsword-devel] IndexVersion metadata clarification

[Sijo Cherian]

Martin,

These java methods are only half baked, so refrain from using them for few
more days.

Take a look at LuceneIndexManager's
boolean needsReindexing(Book book); as the API method to detect if per-book
index need to be recreated.

needsReindexing returns true, if Latest.Index.Version.xxx >
Installed.Index.Version.xxx OR if {book's index folder} is not found at all.

Uses two property files:
1. IndexMetadata.properties (will be packaged with JSword) : specifies the
Latest.Index.Version.xx  (default version & per book index version if
needed)
2. {IndexFolder}/JSword/lucene/InstalledIndex.properties file for
"Installed.Index.Version.book.moduleversion" values that stays persistent
on clients WritableProjectDir : There will be a default version, and a per
indexed book version. JSword will create this file if it does not exist,
and update the version after each book is indexed through IndexManager api.
