Thomas Mueller commented on OAK-319:
------------------------------------
The Jackrabbit 2.x implementation, SimilarityQuery, uses roughly:
{noformat}
MoreLikeThis more = new MoreLikeThis(reader);
more.setAnalyzer(analyzer);
more.setFieldNames(new String[]{FieldNames.FULLTEXT});
more.setMinWordLen(4);
TermDocs td = reader.termDocs(TermFactory.createUUIDTerm(uuid));
Query similarityQuery = null;
if (td.next()) {
similarityQuery = more.like(td.doc());
}
td.close();
{noformat}
The uuid is the uuid of the node. No nodes are returned if the node doesn't
exist.
