I tried to use the completion suggester feature of elastic but when i fill the suggest input field with words with the same prefix it return only one of them.

for example a sample of my document suggest field

"msSuggest": { "input": ["Hair", "Hair loss treatment", "الشعر", "علاج تساقط الشعر"] }

when i write **h** \>\>\>\>\>\>result if Hair **only**  
when i write **hair l** \>\>\>\>\>\>\>result is Hair loss treatment

so not both returned when i input **h**

**The suggest query (Nest)**

var response = await \_elasticSearchClient.SearchAsync(s =\> s  
.Index()  
.Index(new { indexName })  
.Source(x =\> x.Includes(g =\> g.Fields(f =\> f.HgroupsAR, f =\> f.HgroupsEN, f =\> f.Suggest)))  
//.Query(q =\> q.QueryString(qq =\> qq.Query("suggest:_horm_")))  
.Suggest(su =\> su  
.Completion("hgs", cs =\> cs  
.Field(f =\> f.msSuggest)  
.Prefix(query)  
.SkipDuplicates()  
)
