That'd depend on the various settings you have passed into the query, what does your query look like?

this is my query

"suggest":{
"text":"centre",
"simple_phrase":{
"phrase":{
"analyzer":"standard",
"field":"_all",
"size":5,

"max_errors":4,
"confidence":2,
"highlight":{
"pre_tag":"",
"post_tag":""
},
"direct_generator":[
{
"field":"_all",
"suggest_mode":"always",
"min_doc_freq":3,
"min_word_len":1
}
],
"collate":{
"query":{
"match_phrase":{
