Problem using Lucene RangeQuery
I'm using Rangequery to get all the documents which have amount between say 0
to 2. When i execute the query, Lucene gives me documents which have amount
greater than 2 also...What am i missing here?
Here is my code:
Term lowerTerm = new Term("amount", minAmount);
Term upperTerm = new Term("amount", maxAmount);
RangeQuery amountQuery = new RangeQuery(lowerTerm, upperTerm, true);
finalQuery.Add(amountQuery, BooleanClause.Occur.MUST);
and here is what goes into my index:
doc.Add(new Field("amount", amount.ToString(), Field.Store.YES,
Field.Index.UN_TOKENIZED, Field.TermVector.YES));
Thanks.

Lucene stores and searches STRINGS
so range [0..2] may return 0,1,101, ..109, 11, 110, ..119, 12, ....., 2
prefix and normalize your number, like: 001,002...011,012,, 113, etc,
if you'll have bigger numbers, put more 0's
All of these and much more are documented on the wiki, javadocs and so
on, please read them first.
