Retrieving a document from a "keyword" field

[Jean-Albert <we...@mapeo.eu>]

Hello all,

The documents of my (mysql) database are indexed by Lucene, and I save (as a
"Keyword") the database id in the "internal_id" field of the Lucene
document.

If a search my Lucene index, I can read the internal_id and instanciante the
object from the database. Good.

But now I want to know if an object in my database is indexed yet, so I try
to search the following query :
internal_id:399 (399 is the id in the database) , with the hope to get from
Lucene the document having 399 in the internal_id field.

But I get no results. Impossible to retrieve this document...

Do I misunderstood how to search a specific field ?

Hi JA,

The "general@l.a.o" list has fewer subscribers than "java-user@l.a.o", so in the future, I would recommend going there for questions like these.

Can you show the code you're using to search?  My guess is that the analyzer being used is stripping numeric terms, resulting in an empty query.
