What is the percent of size of lucene's index ?
I need to know what is the percent of size of lucene's index respect the
information I'm going to index, I have read some articles that say if a I
index 120 Gb of information the index will grow until 40 Gb, that means the
percent is 30 %, Could somebody tell me how can be proved that ?
Is there any official document of apache lucene where says that ?
I hope somebody can help me.
Thanks.
Ariel

You can also use Luke after you've created your indexes to get their
exact size, and other interesting data points.
Like Ian said though, the decisions you make on a field by field basis
will make your index size vary quite a bit, so probably the best thing
you could do is simply try it out, and then examine it.

I think there are too many variables to give a simple answer.
How much of your data are you storing? Indexing? Compressing?
Get a representative sample of your data and try it out.
