Filtering searchresults by categories

  • Filtering searchresults by categories
  • Hi all,

     I have extended the sitefinity search engine to filter search results by Categories. I found a blog by sitefinity which described how to do this but it's very outdated (2012). 

    The documentation for building a search query does not really exist but I managed to implement it anyway, I thought it could be helpfull to share this information.

     The setup is basically the same as in the blog, only the code for building the query changes:

    public static IEnumerable<IDocument> Search(string term, IEnumerable<string> categories, int take, int skip, out int hitcount)
            
                var searchFields = new List<string> "Title", "Subtitle", "Summary", "Description", "Categories" ;
     
                var searchService = Telerik.Sitefinity.Services.ServiceBus.ResolveService<ISearchService>();
     
                var queryBuilder = ObjectFactory.Resolve<IQueryBuilder>();
                var query = queryBuilder.BuildQuery(term, searchFields);
                query.IndexName = "search-index";
                query.Skip = skip;
                query.Take = take;
                query.OrderBy = null;
     
                if (categories != null && categories.Any())
                
                    var CategoryGroup = new SearchQueryGroup
                    
                        Terms = categories.Select(c => new SearchTerm Field = "Categories", Value = c ),
                        Operator = QueryOperator.Or,
                    ;
                    var SearchGroup = query.SearchGroup;
                    query.SearchGroup = new SearchQueryGroup
                    
                        Groups = new[] SearchGroup, CategoryGroup,
                        Operator = QueryOperator.And
                    ;
                
     
                var result = searchService.Search(query);
                hitcount = result.HitCount;
                return result.SetContentLinks();
            

     

  • Hello Jurgen,

    Thank you for sharing the info with the community. We will look at modifying the blog post to indicate that it is only applicable to earlier versions.

  • I know this is an old post but I would appreciate any sort of feedback here. I managed to successfully compile and install the above custom search widget into my sitefinity website. I am running Sitefinity 8.0 for what its worth. However, it seems the search is not filtering by category because when I search a term, its returning all the files with the term in it regardless of whether they are in the specified category or not. Any insight?

    I'm using the code exactly as above. I made sure to create a search index, to categorize my files, and to reindex. 

     

  • Hi,

    How do I fix the assembly references which was explained in the blog?

    Thanks
