Subject Re: docfaq of IndexReader is showing the deleted document also
Date Tue, 27 Jul 2004 13:58:22 GMT
Hi Raju,

read the documentation for the IndexReader.delete method and you will 
find your way ;-)

/** Deletes the document numbered <code>docNum</code>.  Once a document is
   deleted it will not appear in TermDocs or TermPostitions enumerations.
   Attempts to read its field with the {@link #document}
   method will result in an error.  The presence of this document may 
still be
   reflected in the {@link #docFreq} statistic, though
   this will be corrected eventually as the index is further modified.

public final synchronized void delete(int docNum) throws IOException
