Hi,

Sometimes we get an error in HitSpecification. I guess it's related to ExcerptLength. This is our code:

query.GetResult(
    new HitSpecification
    {
        HighlightTitle = true,
        HighlightExcerpt = true,
        ExcerptLength = 400,
        PreTagForAllHighlights = "<strong>",
        PostTagForAllHighlights = "</strong>",
    });

And this is the error message:

[ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
