_copy_to does not support boosting
Among other properties, analyzer terms and boosting get lost when perfoming the _copy_to
the main _search_all
field. Alternatives to test:
- As mentioned here one option would be to query both the specific boosted field and the
_search_all
. - Move all fields except
_access
inside_search_all
and remove the_copy_to
directive. That way we would reduce space taken by the copied terms plus we could achieve better searches by adjusting properties.
