In general, whether or not you need to re-index largely depends upon the data
that
you are searching, and what was changed in any given Unicode version. For
example,
if you are completely sure that your content is limited to the "Basic Latin"
range
of Unicode, you can safely ignore this.

> 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.
