I have to search in above index for 2 records "amazon" and "walmart" and these records are stored corresponding to field "mrch_nm".
So, basically ,I want muti value search for single field. I have tried above query but getting below result 
"suggest" : {
"simple_phrase" : [
{
"text" : "amazn,walmart",
"offset" : 0,
"length" : 13,
"options" : [
{
"text" : "amazon walmart",
"score" : 5.6008284E-4,
"collate_match" : true
}
]
}
]
}
}
its coming together and without comma separated..so it unclear what is suggestion for "amazon" and what is for "walmart" . There is no separation.
Can anyone help in search for multi value for single field.
P.S: Amazon and walmart are 2 different records in index.
