MemoryIndex "field must not be added more than once"
I'm using a MemoryIndex to search in-memory content.
I was wondering if there's a way to specify multiple values for the same
field in a MemoryIndex.
I've tried addField but it throws an exception:
index.addField("foobar", "value1", LuceneAnalyzer);
index.addField("foobar", "value2", LuceneAnalyzer);
java.lang.IllegalArgumentException: field must not be added more than once
Thanks!

Thanks for your help Uwe. I've created an issue:

Hi,
Can you open a bug report in JIRA about this? The IndexWriter/IndexReader
contract allows to add the same field several times (internally
concatenating, but with a positionIncrement gap). If you append the fields
before, phrase queries may behave differently.

Easiest way to do that would be to append all your values together and then
add them in one pass. Unfortunately, you can only add a field + values
once.
