no segments* file found in Lucene.Net.Store.SimpleFSDirectory@

Question

I've downloaded some samples of Lucene.Net library and tried to run but it always throw this error

no segments* file found in Lucene.Net.Store.SimpleFSDirectory@

It throws an error while creating object at this line,

var searcher = new IndexSearcher(_directory, false)

Is anyone has idea on this? Is there any configuration required to implement this lucene.Net library?

Answer 1

For me it was two issue, 1st this is index was not created so for the 1st time it was throwing this error, Following code resolved that issue.

if (!System.IO.Directory.EnumerateFiles(indexDirectory).Any()) 
{
     return new List<Model>();
}

2nd thing,

Do not forget to dispose object of IndexSearcher , IndexReader and IndexWriter .

Disposing memory of these object in sequence, resolved my issue.
