Solr Suggester component for autocompletion

This JIRA issue and this wiki page imply that there is an up-and开发者_开发知识库-coming component called org.apache.solr.spelling.suggest.Suggester for doing improved auto-complete with Solr. But I'm having trouble trying to find a release that actually has this code.

The wiki says that Solr 3.x and 4.x have include it; is that insider-speak for Solr 1.3 and 1.4 respectively? I'm using 1.4.1 (via Maven), and I see no such component.

Pulling the source from here, I find it in src/java/org/apache/solr/spelling/suggest/Suggester.java. But it fails to build with:

[javac] Compiling 8 source files to /Users/user/Downloads/apache-solr-4.0-2011-02-22_08-06-33/apache-solr-4.0-2011-02-22_08-06-33/contrib/analysis-extras/build/classes

BUILD FAILED
/Users/user/Downloads/apache-solr-4.0-2011-02-22_08-06-33/apache-solr-4.0-2011-02-22_08-06-33/common-build.xml:275: /Users/user/Downloads/apache-solr-4.0-2011-02-22_08-06-33/apache-solr-4.0-2011-02-22_08-06-33/contrib/analysis-extras/lib does not exist.

Is there a way to get a reasonably stable Solr artifact with the Suggester included, preferably via Maven?

Solr 3.x and 4.x are not 1.3 and 1.4.

1.3 and 1.4 are stable releases. 3.x and 4.x are yet unreleased. Versioning scheme changed due to Solr merging with Lucene.

If you need a 4.x build I recommend getting one from the build server.

Also note there are several ways to implement autocomplete with 1.4.1, see Simple Solr schema problem for autocomplete
