示例1: GetAnyTokenStream

        /// <summary>
        /// A convenience method that tries a number of approaches to getting a token stream.
        /// The cost of finding there are no termVectors in the index is minimal (1000 invocations still 
        /// registers 0 ms). So this "lazy" (flexible?) approach to coding is probably acceptable
        /// </summary>
        /// <returns>null if field not stored correctly</returns>
        public static TokenStream GetAnyTokenStream(IndexReader reader, int docId, String field, Analyzer analyzer)
        {
            TokenStream ts = null;

            var tfv = reader.GetTermFreqVector(docId, field);
            if (tfv != null)
            {
                var termPositionVector = tfv as TermPositionVector;
                if (termPositionVector != null)
                {
                    ts = GetTokenStream(termPositionVector);
                }
            }
            //No token info stored so fall back to analyzing raw content
            return ts ?? GetTokenStream(reader, docId, field, analyzer);
        }
