You could for example:

var searchProvider = ExamineManager.Instance.SearchProviderCollection["RegularSearcher"];
//RegularSearcher & PDFSearcher are the names you set up in the <ExamineSearchProviders settings in ExamineSettings.config 
var searchProviderPdf = ExamineManager.Instance.SearchProviderCollection["PDFSearcher"];

IEnumerable<SearchResult> searchResultsAll = searchProvider.Search(searchstring,true);  
searchResultsAll = searchResultsAll.Concat(searchProviderPdf.Search(searchstring,true));

searchResultsAll = searchResultsAll.OrderByDescending(n => n.Score);

Guys,

The latest version of examine has multi index search provider, not used it myself but its there see http://examine.codeplex.com/releases/view/62313

Thank you for the replies. I don't want to combine the search results I am just trying to search each index seperatley. So I have MethodA which searches IndexA and returns results, and MethodB which searches IndexB and returns results. It seems if MethodA uses SearcherA I get the IndexA results, but when MethobB uses SearcherB I get no results. MethodB will only return results if I change the defaultProvider field to SearcherB, but then MethodA doesn't return any results.

Both Lucene queries generated in C# return results in Luke.

I'm going to update to Umbraco 4.7 final and make sure I have the latest Examine dll. I still think you should be able to search 2 indexes with 2 different providers and get back 2 different results, or am I mistaken?

Looking forward to your response :)

Here is my method where I pass in the indexName (plus other parameters)

        public static IEnumerable<SearchResult> Search(string indexName, string[] searchTerms, string[] fields, string[] nodeTypeAliases)
        {
            IEnumerable<SearchResult> results = null;

            if (searchTerms != null)
            {
                // Make sure there are no empty search terms.
                var nonEmptySearchTerms = searchTerms.Where(x => !string.IsNullOrEmpty(x));
                if (nonEmptySearchTerms.Count() > 0)
                {
                    // Get the search criteria by using our searcher provider and looking only in the content tree of Umbraco.
                    var criteria = ExamineManager.Instance.SearchProviderCollection[indexName].CreateSearchCriteria(IndexTypes.Content, BooleanOperation.Or);

                    // Build the search query.
                    Examine.SearchCriteria.IBooleanOperation query = null;                    
                    foreach (var searchTerm in nonEmptySearchTerms)
                    {
                        // Add search fields.
                        foreach (var field in fields)
                        {
                            query = query == null ? criteria.Field(field, searchTerm.Escape().Value.MultipleCharacterWildcard()) :
                                query.Or().Field(field, searchTerm.Escape().Value.MultipleCharacterWildcard());
                        }
                    }

                    // Perform the search.
                    results = ExamineManager.Instance.Search(query.Compile());
                    results = results.OrderByDescending(x => x.Score); // Relevance.

                    // TODO: Do this in the query not sure how yet?
                    if (nodeTypeAliases != null)
                    {
                        results = results.Where(x => nodeTypeAliases.Contains(x.Fields["nodeTypeAlias"]));
                    }
                }
            }

            return results;
        }

We have a very similar method, and... it just work (latest 4.7), ie it picks results for the selected index. But I remember facing a similar issue in the past. Can you check that you do have the latest Examine DLLs?

I tried to upgrade from 4.7RC to 4.7 final. The upgrade all works except umbraco.MacroEngines.dll. I get this message on all my Razor scripts:

Error loading Razor Script *.cshtml Method not found: 'System.Collections.Generic.IEnumerable`1 umbraco.MacroEngines.DynamicNodeList.get_Items()'.

If I use the 4.7RC umbraco.MacroEngines.dll it works.

umbraco.MacroEngines.dll 4.7RC (version 1.0.0.0, size 89Kb) - this works!
umbraco.MacroEngines.dll 4.7 (version 1.0.0.0, size 97Kb) - this doesn't work!

Any one else have this problem?

That works! Quite obvious - thank you :)

Any ideas on the umbraco.MacroEngines.dll error I'm expriencing updating?

@Morten: we indeed do that, and I failed to spot the difference... you're the boss!

Glad it worked. I don't have an answer on the razor issue. sorry.

is working on a reply...
