[Lucene.Net] when indexing I boost certain documents, but their score at search is still 1

[nima dilmaghani <ni...@gmail.com>]

I am trying to boost certain documents. But they don't get boosted. Please
tell me what I am missing. Thanks!

In my index code I have:

if (myCondition)
{
   myDocument.SetBoost(1.1f);
}
myIndexWriter.AddDocument(document);

then in my search code I retrieve the collection of documents from the
ScoreDocs object into myDocuments collection and:

    foreach (Lucene.Net.Documents.Document doc in myDocuments)
    {
        float tempboost = doc.GetBoost();
    }

and I place a breakpoint in the foreach clause to break if the tempboost is
not 1. and the breakpoint is never hit.

What did I miss?

Many thanks!

You missed to read the documentation:
