Inclusion of fields while creating an aliases

Elastic Stack Elasticsearch
1

Hi;
I have some small doubt regarding making an alias on 2 or 3 indexes
that whether or not fields of your choice can be included while making
an alias on individual index like we do in Database views.
Thanks;

Hi;

I am retriving documents using source disabled as follows

{
"fields": ,
"_source": {
"enabled": false
},
"query": {
"term": {
"usersonmail": "ajay.padvi"
}
}
}
but still its showing me all the columns.Please someone clarify how to
achieve retrieval of only wanted columns from an alias.

Thnks

Disabling the source is done on the mapping side. When you create an index,
you can have mappings for types, on them, you can disable storing the
source.

On the search side, even if _source is stored, you can set "fields" to an
empty array, in which case the response will not include any fields (except
for the id).

Hi shay;

Thanks for your reply.I disabled the source at mapping and getting
appropriate results in search DSLs,But my requirement is to create a view
like structure/alias on index so that i can specify those field to be shown
during an alias creation time only like we do in SQLs views.But as far as i
have observed an alias only supports filter and i was not able to specify
wanted fields to be retrieved by any means in alias "add" action.
The problem is related to database search where in where in i want to
specify only those columns mapped according to privileges.

Please share and provide me some inputs whether can it be done in
elasticsearch or not for which i will be very obliged.

Thnks;
Arien.

Aliases are not similar to SQL views, so you can't really ask only for
those aliases to have specific fields, and have _source disabled in the
actual index. Think of an alias as a simple way to alias an index with a
different name, possibly adding the ability to automatically apply a filter
and routing when searching / indexing.
