Hi Ismail,

thanks for replying that quickly. I'm trying it out, but maybe I'm missing something:

SearchTerm.MultipleCharacterWildCard() doesnt work with me because SearchTerm is a protected string SearchTerm { get; private set; }

Do I need to include a reference to the extensionlibrary? It should be a string right? Not a IExamineValue?

Thanks a lot!

a last question, where do I input the IbooleanOperation query?

somewhere in here?

var filter = criteria 
                   .GroupedOr(new string[] { "nodeName", "naamArtikel", "omschrijving" }, SearchTerm.ToLower())
                   .Not()
                   .Field("umbracoNaviHide", "1")                   
                   .Compile();

where you have SearchTerm.ToLower() just add the MultipleCharacterWildCard() so you have

SearchTerm.ToLower().MultipleCharacterWildCard()

Hi Ismail,

thanks for the reply. The wildcards' working now.

But putting the * before the word doesnt work. So now I can search ' larger* ' and find 'largerword'. But I cannot search ' *word ' and find 'largerword'

Any ideas?

I'm hoping this post will help me as I have the same issue.

To answer your last question Martin, a wild card is not permitted at the start of a search, http://lucene.apache.org/java/2_3_2/queryparsersyntax.html

I learned that already, but thanks anyway.

It's just a weird not really thought out issue with lucene.

although I heard that it is possible to enable it, but hten you have to extend the examine class.

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

the MultipleSearchCriteria extension is hidden somewhere deeper within the examine namespace, because otherwise the string extension would pop up everywhere.

I think you only have to add:

using UmbracoExamine.SearchCriteria.LuceneSearchExtensions

Then it will work

Adding that does not work.  LuceneSearchExtensions does not exist in that namespace.

Does anyone have an answer to the MultipleCharacterWildCard extension is.  I am trying to use it but can't find where it is.

Hmmm this may not help you but I looked back at what I did and ended up using .Fuzzy() instead.

I'm just searching for the first initial of a name so don't really need fuzzy.

But for anyone finding this in the future it seems to be in Examine.LuceneEngine.SearchCriteria.

is working on a reply...
