hi
I have a code that work fine with lucene 3.2 where i used TermDocs to find
the corpusTF here is the code
public void calculateCorpusTF(IndexReader reader) throws IOException {
// TODO Auto-generated method stub
Iterator it = word.iterator();
Iterator iwp = word_prop.iterator();
wordProp wp;
Term ta = null;
TermDocs tds;
// DocsEnum tds;
String text;
tfDoc tfcoll;
long freq=0;
OpenBitSet skipDocs = null;
skipDocs = new OpenBitSet(0);
//System.out.println("Length: "+skipDocs.length());
try {
while(it.hasNext())
{
text=it.next();
wp=iwp.next();
System.out.println("Word is "+text);
ta= new Term("content",text);
//BytesRef term = new
BytesRef(text.toCharArray(),0,text.length());
tfcoll = new tfDoc();
freq=0;
tds=reader.termDocs(ta);
//
tds=reader.terms("content");
if(tds!=null)
{
while(tds.next())
{
freq+=tds.freq();
//
System.out.print( text +" "+ freq);
}
}
// New Code -->
// tds = reader.termDocsEnum(skipDocs, "content",
term);
// if(tds!=null)
// {
// while(true) {
// freq += tds.freq();
// final int docID = tds.nextDoc();
// if (docID ==
DocsEnum.NO_MORE_DOCS) {
// break;
// }
// }
// }
//
// New code Ends <--
tfcoll.tfA=freq;
System.out.print( text +" "+ freq);
if(tfcoll.totalTF()==0)
{
//System.out.println(" "+tfcoll.tfA+"
"+tfcoll.tfD+" "+tfcoll.tfC);
System.out.println("Text "+text+ " Freq
"+freq);
}
wp.tfColl=tfcoll;
}
}
catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
}
but now i have to use TermDocEnum because i am using lucene dev4.0 which
does not have TermDocs method i was trying to change my code .please refer
to new code [commented ] and tell me how to use this method in a proper way
. if you can provide an example that would be great.
tds = reader.termDocsEnum(skipDocs, "content", term);
I have tried using null at skipdoc because i don't want to skip anything but
it through error
please help
