I'm considering building out an index that will flatten a data

such that some Document "A" will have Fields 1,2 and 3.
Fields 1 and 2 are indexed/tokenized field. Field 3 is indexed, and
will
contain many discrete values (up to possibly 5000).
Couple of questions:
1. Does the DEFAULT_MAX_FIELD_LENGTH on IndexWriter come into play
for Field
3? Field 3 values are added to the document individually, there's
just a
bunch of them.
No. The max field length only comes into play for tokenized
(analyzed) fields.
2. Is MaxFieldLength a consideration for this?
The default is 10,000, so you're safe :)
From IndexWriter.java:
public final static int DEFAULT_MAX_FIELD_LENGTH = 10000;
Any guidance before I go through the trouble of building the index
would be
greatly appreciated.
Never be afraid to just try out things. It's easy enough to whip up
a simple Java program of only a few lines that would exercise this
sort of thing. A simple for loop adding 5000 identically named non-
tokenized, indexed fields to a document would prove this to yourself.
And now with Ferret - http://ferret.davebalmain.com/trac/ - the fun
and lightweight nature of Ruby will allow us to experiment with
Lucene without even compilation (or suffering Python syntax :).
