Hi guys,

I am attempting to implement a section of examine search code that was written for me into a new website.  I have updated the examinesettings and config files as well as ensuring all datatypes are included, but when I run the search on the front end of the website I am getting the error message below..

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 171

Any ideas, for info this is on version 7 and the code being used is below:

 

@{

                System.Xml.XPath.XPathNodeIterator iterator = umbraco.library.GetPreValues(1093);

                iterator.MoveNext();

                System.Xml.XPath.XPathNodeIterator preValues = iterator.Current.SelectChildren("preValue", "");
