    Examine - Getting IndexSetName from Searcher

    HI folks,

    I would like your help on extracting the IndexSetName from a Searcher. You can see the IndexSetName is available under each searcher. You can see this in ProviderProperties.

    The reason I'm doing this I'm developing a plugin/package where you choose a Searcher e.g ExternalSearcher, InternalSearcher or any other.

    I have to get the IndexSetName to create an event handler for GatheringNode. 

    ExamineManager.Instance.IndexProviderCollection["ExternalIndexer"].GatheringNodeData += MediaSearchController_GatheringNodeData;

var Searcher = ExamineManager.Instance.SearchProviderCollection["ExternalSearcher"];

    I'm trying to avoid hardcoding the name of the Searcher (ExternalSearcher) and IndexSetName (ExternalIndexSet).

    So I would select ExternalSearcher from a dropdown and it passes this name "ExternalSearcher" as a variable SearcherTypeName into the SearchProviderCollection.

    var Searcher = ExamineManager.Instance.SearchProviderCollection[SearcherTypeName];

    I need to do the same for ExamineManager.Instance.IndexProviderCollection["ExternalIndexer"]

    How I get the IndexSetName from my choice of Searcher i.e. "ExternalIndexer"?

    Is there a better of getting the IndexSetName? Would ExternalSearcher and ExternalIndexer always be available in all of Umbraco 7 installations?

    Can you please help?

    Update: This is what I can see from the Searcher properties. It's a bit limited

    John,

    I have done with indexers and you have to cast it to LuceneIndex then you can get to the properties, I suspect you have to do something similar for searcher? Take a look at examine code and see what base class searcher implements.

    Regards

    Hi Ismail,

    That fixed the issue. You've pointed me in the right direction. I needed LuceneSearcher.

    var searchIndexer = (Examine.LuceneEngine.Providers.LuceneSearcher)ExamineManager.Instance.SearchProviderCollection[2];

var indexSetName = searchIndexer.IndexSetName;

    With this code, I was able to get the IndexSetName.

    Thanks for your help, Ismail! :)
