Hi Brian,

in ExamineSettings.config:

It seems if you have only set your Indexer in ExamineIndexProviders . But you must also insert the Searcher, in ExamineSearchProviders like this:

 <add name="PropertySearchSearcher" type="UmbracoExamine.UmbracoExamineSearcher, UmbracoExamine"
      analyzer="Lucene.Net.Analysis.Standard.StandardAnalyzer, Lucene.Net" enableLeadingWildcard="true"/>

 

And rename your IndexSet in ExamineIndex.config from PropertySearch to PropertySearchIndexSet. The naming conventions are important!

 

Best regards

Sören
 

The search section and result section are non-essential at this time. If you have 0 records in your Index then it is most likely a configuration issue.

Hi Soren,

Thanks for the information, must admit that most of the reasoning behind this is not making sense to me at the moment, hence the floundering!

I have amended my ExamineSettings file as recommended but this causing my whole site to crash, am I missing something?

Also, when you say that something is wrong with my configuration where abouts should I be looking?

 

This is the code I now have for my ExamineSettings file:

 

<?xml version="1.0"?>

<!-- 

Umbraco examine is an extensible indexer and search engine.

This configuration file can be extended to add your own search/index providers.

Index sets can be defined in the ExamineIndex.config if you're using the standard provider model.

Hi Soren,

Slowly getting somewhere..

I removed the following from my Examineindex.config file and I now have 29 nodes found:

<IncludeNodeTypes>

      <add Name="PropertyDetails" />

    </IncludeNodeTypes>

So looks like I was somehow referencing an incorrect doc type although that is exctly what it was called (any ideas on why, assuming it's important to the solution)

 

When I now run a search on the site I now get the following error on the results page:

System.ArgumentNullException: Value cannot be null. Parameter name: s at System.IO.StringReader..ctor(String s) at Lucene.Net.QueryParsers.QueryParser.GetFieldQuery(String field, String queryText) at Lucene.Net.QueryParsers.MultiFieldQueryParser.GetFieldQuery(String field, String queryText, Int32 slop) at Examine.LuceneEngine.SearchCriteria.LuceneSearchCriteria.GetFieldInternalQuery(String fieldName, IExamineValue fieldValue, Boolean useQueryParser) at Examine.LuceneEngine.SearchCriteria.LuceneSearchCriteria.FieldInternal(String fieldName, IExamineValue fieldValue, Occur occurance, Boolean useQueryParser) at Examine.LuceneEngine.SearchCriteria.LuceneSearchCriteria.FieldInternal(String fieldName, IExamineValue fieldValue, Occur occurance) at ASP._Page_Views_PropertySearch_cshtml.Execute() in c:\HostingSpaces\bmhwebdesign\letitbeproperties.com\wwwroot\Views\PropertySearch.cshtml:line 53

And just for reference this is where I have set files up (again I am a total nooby at this so may well have missed out something vital!!)

1. set up initial search code (see below)

2. set up results query code (see below)

3+4 amended examinindex config and examine settings config to include the new search tool (see below for each)...  

Have I missed any important steps out for setting up an examine based search tool?

Hi Brian,

Your indexer have the name "PropertySearchIndexer". Because of that I think your searcher in examinesettings.config must have the name "PropertySearchSearcher" instead of "PropertySearcher".
