-------------------------------------
[~teofili] do you know where documentation about supported / unsupported characters for Lucene can be found?

> Key: OAK-4080
> URL: https://issues.apache.org/jira/browse/OAK-4080
> Project: Jackrabbit Oak
> Issue Type: New Feature
> Components: query
> Reporter: Thomas Mueller

> Currently, "jcr:contains" with special characters don't work the same when using a Lucene fulltext index compatVersion 2 compared to using compatVersion 1 or Jackrabbit 2.x.
> This needs to be documented. Also, it might make sense to provide a compatibility flag, so that behavior is the same as with the old versions, at least as much as possible, even thought new features would not be supported.
> The one example I know is using "\*" as in:
> {noformat}
> SELECT * FROM [nt:base] AS c WHERE CONTAINS(c.[test], 'athxv:!*')
> {noformat}
> With compatVersion 2, the "\*" needs to be escape as follows, in order to match properties with exactly this text:
> {noformat}
> SELECT * FROM [nt:base] AS c WHERE CONTAINS(c.[test], 'athxv:!\*')
> {noformat}
