Hi,

Is there a way to analyze a field that is passed to the context suggester?  
If, say, I have this in my mapping:

```
mappings: {
    myitem: {
        title: {type: 'string'},
        content: {type: 'string'},
        user: {type: 'string', index: 'not_analyzed'},
        suggest_field: {
            type: 'completion',
            payloads: false,
            context: {
                user: {
                    type: 'category',
                    path: 'user'
                },
            }
        }
    }
}

```

and I index this doc:  
POST /myindex/myitem/1  
{  
title: "The Post Title"  
content: ...  
user: 123  
suggest\_field: {  
input: "The Post Title",  
context: {  
user: 123  
}  
}  
}

I would like to analyze the input first, split it into separate words, run  
it through lowercase and stop words filters so that the context suggester  
actually gets  
suggest\_field: {  
input: ["post", "title"],  
context: {  
user: 123,  
entity: 'posts'  
}  
}

I know I can pass an array into the suggest field but I would like to  
avoid lowercasing the text, splitting it, running the stop words filter in  
my application, before passing to ES. If possible, I would rather ES do  
this for me. I did try adding an index\_analyzer to the field mapping but  
that didn't seem to achieve anything.

OR, is there another way to get autocomplete suggestions for words?

Cheers,  
Dan
