Subject merge problems
Date Tue, 04 Oct 2016 14:40:37 GMT
After upgrading to 6.2 we are having problems during merges (after running
for a while).

When the problem occurs its always complaining about the same field - and
throws:

java.lang.IllegalArgumentException: field="id" did not index point values

To figure out where we messed up - I have added some ugly logging to
Document:

public final void add(IndexableField field) {
        if ("id".equals(field.name()) &&
                field.fieldType().pointDimensionCount()
                        != 0) {
            System.err.println("Point value detected");
            for (IndexableField i : fields) {
                System.err.println(i);
            }
        }
        fields.add(field);
  }

In hope to intercept the document we messed up.

But to my surprise toString on the suspected field just says (contains a
URN):

indexed,omitNorms,indexOptions=DOCS<id:urn:wiki:doc:YEL:57028#1-1>

So any hints as to why field.fieldType().pointDimensionCount() != 0

and any suggestions what might cause this?
