Hello!

Could you be more specific what you would like to get from ElasticSearch ? In case of match_all query, you are basically saying, that you are interested in all the documents and not any particular data.

Hi

there are couple of options you can try.

a) if you did not disable _source field then you can get the whole field
content from it, for example you could use fields [1]
b) If your 'description' field is too long and you need to make it shorter
then you can either post-process it at the client side or try to use script
field [2]

What we do is that for each document we have a 'description' field that is
used in similar use case (i.e. query does not match any of fields that are
used to produce highlights). When users push documents into the search
server they can setup the 'description' field and they know that this value
will be used (i.e. displayed) if no highlights are created. So it is
something like a pitch field :slight_smile: and we get this field using 'fields' [1]
while the 'description' field is stored.

Lukas
