You need to pass in the IExamineValue object, not the generated string, otherwise Lucene doesn't know it's a wildcard query you're trying to cut and it'll strip out the '*' as it deems it illegal

Thanks for the reply slace, but I'm not sure I understand.

I am not adding any '*' manually, as I know that won't work. That's why my code has 'MultipleCharacterWildcard()'.

The searchcriteria valus I listed are generated, and I wanted to know how to get the wildcard behaviour when using StandardAnalyzer.

You're accessing the Value property of the IExamineValue, that's returning just a string so it's not being treated as a Lucene object by the analyzer

No no, I just had that value printed to the page and listed here to show what happens when I leave my code untouched but change the analyzer.

This is the actual code:

        protected void Page_Load(object sender, EventArgs e)
        {
            SearchTerm = Request.QueryString["s"];
            if (string.IsNullOrEmpty(SearchTerm)) return;
            
            var criteria = ExamineManager.Instance
                    .SearchProviderCollection["InternalSearcher"]
                    .CreateSearchCriteria(UmbracoExamine.IndexTypes.Content);

            var filter = criteria
               .GroupedOr(new string[] { "nodeName", "docTitel", "docKort", "docTekst" }, SearchTerm.MultipleCharacterWildcard().Value)
               // .Not().Field("umbracoNaviHide", "1")
               .Compile();

            litExamine.Text = String.Format("\n\n<!-- {0} -->\n\n", criteria.ToString());

            SearchResultsList =
                ExamineManager.Instance.SearchProviderCollection["InternalSearcher"].Search(filter);

            SearchResultListing.DataSource = SearchResultsList;
            SearchResultListing.DataBind();

        }

Thank you so much slace, both for your help here and Examine itself.

I can't believe I missed that '.Value'! Odd that it worked fine with .Value using the WhitespaceAnalyze though.

It's because when the WhitespaceAnalyzer parses the query it doesn't remove the '*' from it, but the StandardAnalyzer will remove it.

Can somebody tell me what I'm doing wrong?

It won't recognise MultipleCharacterWildcard() as a valid string extension so I cannot compile it.

I have references to Examine & UmbracoExamine and the folowing code:

using Examine;
using Examine.SearchCriteria;

private void PerformSearch(string searchTerm)
        {
            if (string.IsNullOrEmpty(searchTerm)) return;
            
            var criteria = ExamineManager.Instance
                .SearchProviderCollection["SiteSearchSearcher"]
                .CreateSearchCriteria(UmbracoExamine.IndexTypes.Content);

            var filter = criteria
                .GroupedOr(new string[] { "nodeName", "browserTitle", "metaKeywords", "metaDescription", 
                    "featureTitle", "featureSummary", "title", "searchKeywords", "summary", "body", "footer" }, searchTerm.MultipleCharacterWildCard())
                .Not()
                .Field("umbracoNaviHide", "1")
                .Compile();

            SearchResults = ExamineManager.Instance
                .SearchProviderCollection["SiteSearchSearcher"]
                .Search(filter);

            searchResultsRepeater.DataSource = SearchResults.Skip(CurrentPage * _pageSize).Take(_pageSize);
            
            searchResultsRepeater.DataBind();

        }

Thanks, Matt
