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);
