Is it possible to do a text query against a (pre)defined set of fields?
Hi,
I am indexing some large documents in an index. When making full text
queries, I've generally used {text: {_all: some text search}} to find
all possible results. However, the document contains a few private fields
that should be queryable only by a certain user group.
What I was wondering is if there is a possibility to define some kind of
alias for a set of fields (or even better - all fields except the set of
fields) in the mapping definition. I could then do a query {text:
{alias_for_public_fields: some text search}} while the private fields
would not be searched for. I do not know if this is possible already now?
I know that it's possible to list all fields in the query and leave out the
privates, but as there can be hundreds of fields that should be queryable
but only 2-3 private fields, listing fields explicitly adds significant
overhead to the queries.
Best regards,
Ville

Ville, Perhaps: Don't include the private fields in _all. Then a query against _all would be restricted to the (perhaps hundreds) of public fields. A query that includes the private fields would need to list _all and then the private fields. But since you have only 2 or 3 private fields, there shouldn't be much overhead on the query.

Hi, Well - I think I've understood something wrong here. Isn't _all a special key that includes all indexed fields? Is there possibility to change the fields included in _all?

Ville, By default, the _all field includes all of the indexed field. Then, for your private fields, explicitly exclude them from the _all field by adding the following to their properties: include_in_all : false See the ES guide for more details, Specifically, thishttp://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-all-field.htmlmight help. I typically disable the _all field completely to cut down dramatically on disk space and build times. But everything else in ES has worked like a charm, so I'm sure this would work for you without too much trouble. Good luck!
