We ahve an index with a completion field for autocomplete look ups.  
Is there any way of using a wild card search as opposed to a prefix to search the index.

Our index is very small (100,000 records).  
Thanks

```auto
var searchResponse = client.Search<Locality>(s => s
        .Size(MAX_SUGGESTIONS)
        .Suggest(ss => ss
            .Completion("suggestions", c => c
                .Field("localitySuggestions")
                .Size(MAX_SUGGESTIONS)
               // .Prefix(prefix)
               .Regex($".*{prefix}*")
            //.SkipDuplicates()
            //.Contexts(ctxs=>ctxs/*.Context("country", ctx => ctx.Context("ie").Boost(3))*/.Context("flags", ctx => ctx.Context("13").Boost(3)))
            )
        ).Index(index)
    );
return searchResponse;

```

Hi @xef,

I just asked this question internally and we don't think this is possible with completion suggesters at all.

The documentation as well does not mention anything like this:

> **[Suggesters | Elasticsearch Guide \[8.15\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-suggesters.html#querying)**
