Robert Muir commented on LUCENE-2073:
-------------------------------------
Hello, whereever we put this text (i do not care), I thought the following
would be a start.
please help me make it easier to digest/understand
{noformat}
If possible, use the same major JVM version at both index and search time.
Different JVM versions may implement different versions of the Unicode
Standard, which will change the way Lucene treats your text.
For example, under Java 1.4, LetterTokenizer will split around the character
U+02C6, but under Java 5 it will not.
This is because Java 1.4 implements Unicode 3, but Java 5 implements Unicode 4.

> Document issues involved in building your index with one jdk version and then
> searching/updating with another

> If there is nothing we can do here, then we just have to do the best we can -
> such as a prominent notice alerting that if you transition JVM's between
> building and searching the index and you are using or doing X, things will
> break.
> We should put this in a spot that is always pretty visible - perhaps even a
> new readme file titlted something like IndexBackwardCompatibility or
> something, to which we can add other tips and gotchyas as they come up. Or
> MaintainingIndicesAcrossVersions, or
> FancyWhateverGetsYourAttentionAboutUpgradingStuff. Or a permanent
> entry/sticky entry at the top of Changes.
