Hi, Is there a way to tell the context suggester to display results for all
the categories ?
I know that for the category suggester query I must provide context/s
Sort of:
{
"suggest" : {
"text" : "m",
"completion" : {
"field" : "suggest\_field",
"size": 10,
"context": {
"color": "\*"
}
}
}
}
This should work like simple completion suggester no matter what "color"
each document has.
So I should be able to find suggestions, and filter them (by "color") only
when needed.

Hey,
you could simply index an 'all' color field value for every document, and
then use that for your suggestions?

Thank you Alex,
I also came up with that idea, but I think it is not that useful when you
have context, mapped to a field, which usually contains a single value,
especially numeric fields (despite that
[https://github.com/elasticsearch/elasticsearch/issues/6512](https://github.com/elasticsearch/elasticsearch/issues/6512) is not fixed yet)

Hey,
maybe the new transform feature could help here to create a default value
(just an idea, havent tested it). See

Thanks Alex,
I made it 🙂
I'm using transformation script to add "\*" to any of the context fields.
But I definitely think that issues:

have to be fixed
Probably also provide some way to select any value also for non-string
fields (if issue 6512 end up as toString conversion)
