--- Comment #8 from David Gustafsson <glask...@gmail.com> ---
I might be mistaken, I will try to look it up to be certain. But I think when
using the query string query in Elasticsearch, the default_field parameter is
set to "*.*" as default, so all fields are searched anyway. No need to copy all
fields to yet another field, this will also have a negative impact on search
performance without improving accuracy, and increase the size of the index.
Also, for field boosts to work (title:(title search)^2, each field must be
queried individually. A better solution would be to just remove "_all", and
even better to produce a relevant list of fields for setting the
"fields"-parameter (excluding sortable and facetable fields for example). I
will start working on a patch taking this approach, so will probably have a
proposal ready quite soon.
