Hi all - I am trying to implement a search in which I want to perform  
search over a few pre-defined fields and I do not want to specify those  
fields in my query every time (since the request size might become big). In  
order to do this, I can think of two options:  
\*  
\*  
_Option 1_: Set "include\_in\_all" on the fields that I want to include in  
"\_all" and then execute my search over "\_all' field. The problem I see in  
this approach is I have no control how each of the fields are getting  
analyzed when they merge into "\_all". My understanding is that the entire  
"\_all" field has just one way of analysis and I cannot control analysis of  
components which comprised "\_all"

"phone": {  
"type": "string",  
"include\_in\_all": true //Okay, but how do I control  
analysis when it gets included in \_all  
}  
\*  
Option 2\*: This is where I can create a totally new multi\_field and then  
specify how each of the entities, that would go in this new field will get  
analyzed.

"phone" : {  
"type" : "multi\_field",

```
        "fields" : {
            "phone" : {"type" : "string", "index" : "not_analyzed"},

            "*my_composite_field*" : {"type" : "string", "index" :

```

"analyzed"}

```
        }
    },

```

"fixedLine" : {

```
        "type" : "multi_field",
        "fields" : {

            "fixedLine" : {"type" : "string", "index" : "not_analyzed"},

            "*my_composite_field*" : {"type" : "string", "index" :

```

"analyzed"}

```
        }
    }

```

I believe here that "_my\_composite\_field_" will contain _both_ fixedLine  
and phone values in a way that I want them to be analyzed. Is that right?

-Amit.
