Not necessarily a false alarm...since you *should* be able to index such a creature. Full text should certainly be able to contain whitespace characters, and the lucene reader/filter or your own reader/filter should strip them out. I was under the impression that the default reader/filter was supposed to handle whitespace.

It turns out that the actual field name that I was using was "Comment\n" (literal newline at end of string), not "Comment". We do not have a requirement to index properties with newlines in their name, so you can ignore this post. Thanks for looking it to it. -Paul If anyone still wants the test program, here it is: import org.neo4j.graphdb.GraphDatabaseService; import org.neo4j.graphdb.Node; import org.neo4j.graphdb.Transaction; import org.neo4j.index.lucene.LuceneIndexService; import org.neo4j.kernel.EmbeddedGraphDatabase; public class Comment { private static GraphDatabaseService graph; private static LuceneIndexService indexService; public static void main(String[] args) { graph = new EmbeddedGraphDatabase("./graph.comment"); indexService = new LuceneIndexService(graph); Transaction tx = null; try { Node node; tx = graph.beginTx(); node = graph.createNode(); setProperty(node, "Foo", "Bar"); tx.success(); tx.finish(); tx = graph.beginTx(); node = graph.createNode(); setProperty(node, "Comment\n", "This should be no different."); tx.success(); tx.finish(); } catch (Throwable e) { e.printStackTrace(); tx.failure(); tx.finish(); } indexService.shutdown(); graph.shutdown(); } private static void setProperty(Node node, String key, String value) { node.setProperty(key, value); indexService.index(node, key, value); } } -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Mattias Persson Sent: Tuesday, October 12, 2010 3:46 AM To: Neo4j user discussions Subject: Re: [Neo4j] Exception when adding a "Comment" property to a node Seems like your index key contains characters illegal on your current file system... would it be possible to see the code? or could you supply which index keys you use to index your comments? 2010/10/12 Tobias Ivarsson <[email protected]> > Hi Paul, > > Comment is not a reserved word, there are no reserved words for what > property keys you can use. > > Are you also indexing that "Comment" property?
