-------------------------------------

I found that Elastic indexes are also affected. Working on a fix.

> I've experienced this behavior und the following circumstances:
>  * Query with an index tag option ("option (index tag x)")
>  * The index the tag has an regex property with REGEX_ALL_PROPS
> What happens is that the resulting query to lucene, which can be inspected in [1] is:
> {noformat}
> +:ancestors:/test +:indexTag:x{noformat}
> So the {{:indexTag}} will be added to the Lucene index as a property, because {{:indexTag}} matches the regex, which can be inspected in [2]
> I've added a failing unit test for this in [0].
> I've also tried to come around with a custom regex which excludes every node which starts with a colon ( regex: {{{}"^[^:\\/][^\\/]*$"{}}}). This leads to another problem where the index won't be selected (because the potential propery ":indexTag" does not matches the regex) and the query will traverse.
