Hi everybody,

Using Javascript, I want to create an Index in Elasticsearch from a csv file.  
I put the name of each column (header) in a different position of an array and every field of each  
row in another array. How should I "fill" the body of the index? Let's say  
a have:

arr\_1 = [row1, row2, row3, row4];  
arr\_2 = [field1, field2, field3, field4];

then I want something like:

client.index(  
index: name\_index,  
type: name\_type,  
body: {  
row1 : field1; //arr1\_[1] : arr\_2[1],  
row2 : field2; //arr1\_[2] : arr\_2[2],  
.....  
....  
})

My (wrong!!!) solution is more or less:

for (var i = 0; i \< arr\_1.length; i++){  
row = arr\_1[i];

```
field = arr_2[i]:

var bodyContents = {
    row : field /*this should give me at the end row1 : field1; //arr1_[1] : arr_2[1],

                                                           row2 : field2; //arr1_[2] : arr_2[2],

```

..... }; } client.index( { index: index\_name, type: type\_name, body:  
bodyContents }, function (error) { [.....]

```
}

```

);

Can anyone help me in some way? thanks in advance.
