Im trying to query a with standard analyser using the bleow code (shortened)

var sc = ExamineManager.Instance.CreateSearchCriteria();
var query = sc.NodeTypeAlias("Job");

if (!string.IsNullOrEmpty(sector))
{
    query.And().Field("jobIndustry", sector);
}

var results = Examine.ExamineManager.Instance.SearchProviderCollection["JobSearcher"].Search(query.Compile());

which gives when ToString() is called:

{ SearchIndexType: , LuceneQuery: +__NodeTypeAlias:job +jobIndustry:IT }

All as expected but it returns no results when i know it should.

I tried the raw query in Luke and it looks like the "+jobIndustry:IT" gets dropped. I expect the reason is "IT" is considered a noise word, but in this case it is not. Does anybody know how to fix this by maybe altering the dictionary of noise words where "IT" is allowed. Where would i find the file that is loaded? Any ideas would be appreciated.

PS. I cannot change the word IT as it comes from  a third party feed.

Cheers,

Mark
