I assume what you mean is formatting the number so that the
lexicographical order of any possible sequence of acceptable numbers
is the same as its numerical order.
You must find a canonical representation like the scientific notation

is made so that it can express all long values (64 bits), I *th

Hi Sergey,
quite a lot of numbers are possible for BigDecimal. Somehow the range
must be bounded.
Let's first draw the line where, for a given BigDecimal bd, the result
of bd.toString(), whic
Thanks Ian
Unfortunately, I have to index any possible number of java.math.BigDecimal
I can rephrase my question this way:
How can I convert java.math.BigDecimal numbers in to string

Hi
Lucene only indexes strings.
Hi
Lucene only indexes strings. The standard advice for numeric is to
pad to desired width with leading zeros, if likely to be used in range
searches. How varied are the numbers you're going to be working with?
I only work with stuff with 2 decimal places and tend to lose that.
e.g.

Hello
I want to ask community an advice:
what is the best way to index and search java.math.BigDecimal values in
lucene 2.4.
Any code snippets are welcome.
