I don't believe that this is possible. Or desirable. Lucene IDs are mutable,
even within an index. That is, if you index docs that get, say, IDs 1, 2, 3,
4, 5 and delete doc 2 and optimize, Docs 4 and 5 get reassigned IDs 3 and 4
(or something similar).

You're far better off controlling this yourself. That is, forget Lucene IDs
and make up your own unique IDs that you can guarantee form disjoint sets
across your multiple indexes, then work with those.

Hello,

Is there a way to influence lucene's generation of ids while indexing.

my requirement is. I want to have different indexes where no index should
have
ids that have been assigned to an index earlier.
for instance
IDX1 : {0.........100}
IDX2: {101.......200}
IDX3: {201.......300}
but not
IDX1 : {0.........100}
IDX2 : {0.........100}
IDX3 : {0.........100}

any help is greatly appriciated.
