Hi everybody,

I have the requirement to support searching for numbers with their
alphabetic or by digits.
For example, if we have a document with a field's value of '200',
if we search for "two hundred", that document should match.

I haven't found anything like this yet. Do we have other option than
define the most common numbers and their string versions as
synonyms?

Thanks

You can certainly do a modest number of special cases as replacement
synonyms, but if you are serious about arbitrary number support, it might be
best to go with a custom update processor and query preprocessor that map
text numbers to simple numeric form.

How about cases like 2,300 or 2,300.00 (embedded commas or even decimal
point) - two thousand three hundred or 23 hundred or twenty three hundred?

Or 200 million vs 200,000,000 vs. 200000000?

In any case, synonyms get really messy really quickly, but with
preprocessors you can do whatever you want

the lucene test-framework actualy contains a class named
org.apache.lucene.util.English which can convert int->String in english
text.

You could try wrapping that up in a TokenFilter?
