Hi,
(With "full-text parsing" I understand parsing a full-text expression,
which consists of one or multiple "contains" conditions, into a
FullTextExpression AST. If you have a different understanding, then please
tell me.)
Full-text parsing was originally needed internally (and was not public) in
the query engine, to support the case where no full-text index is
available. But then we improved and moved those classes to the QueryIndex
API (Filter.getFullTextConstraint) to support query-time aggregation. I
think we still want to support query-time aggregation, so we need to keep
it there. I understand we want to use index-time aggregation by default,
the same as Jackrabbit 2.x, but I don't think we want to drop support for
query-time aggregation, at least not yet yet.
As for the "mountain is big" example, the problem seems to be the
query-time aggregation, not the parsing of the expression in the query
engine, and not the use of the FullTextExpression. If you want to get the
term "mountain is big" from the FullTextExpression, use
FullTextExpression.toString() ("Get the string representation of the
condition.").
Regards,
Thomas
