Examine search criteria with wildcards

Questions

Hi,

I try to create a search criteria with wildcards for an autocomplete search.

How can I use wildcard search if I make my own search criteria like this:

var criteria = ExamineManager.Instance
                    .SearchProviderCollection["ExternalSearcher"]
                    .CreateSearchCriteria();

                string[] dynquery = new string[] { query };
                if (multipleGroupedOr)
                {
                    dynquery = query.Split(multipleGroupedOrSeparator);
                }

                var crawl = criteria.GroupedOr(fieldnames, dynquery)
                    .Not()
                    .Field("umbracoNaviHide", "1")
                    .Not()
                    .Field("nodeTypeAlias", "Image")
                    .Compile();

                ISearchResults SearchResults = ExamineManager.Instance
                    .SearchProviderCollection["ExternalSearcher"]
                    .Search(crawl);

 

MultipleCharacterWildcard() on dynquery doesn't work.

var crawl = criteria.GroupedOr(fieldnames, dynquery.MultipleCharacterWildcard())
                    .Not()
                    .Field("umbracoNaviHide", "1")
                    .Not()
                    .Field("nodeTypeAlias", "Image")
                    .Compile();

 

Thanks for any help!
