Re: question about getting all terms in a section of the documents

Donna,

You are correct, "enum" should be "terms".  Could you please modify the FAQ?  
You just have to log into Wiki and edit that page (the edit link is at the 
bottom).

Thanks,
Otis

Subject: question about getting all terms in a section of the documents

I am a very new user of Lucene, and thus far am amazed at its speed and 
ease of use.
I have a question about something in the FAQ though. I have a need to get 
all
terms in a specific section of the document; I want to create a database 
of term vs
an identifier of the document containing the term. There is a part of the 
FAQ which
answers this directly, and says:
try
{
    TermEnum terms = indexReader.terms(new Term("FIELD-NAME-HERE", ""));
    while ("FIELD-NAME-HERE".equals(enum.term().field()))
    {
        // ... collect enum.term().text() ...

        if (!terms.next())
            break;
    }
}
finally
{
    terms.close();
}

However, this doesn't compile for me; Is "enum" supposed to be "terms"? 
Also, the terms.close()
statement is outside the scope of terms. I changed to the following, is 
this correct and should the
FAQ be changed?

try
                {
                    TermEnum terms = indexReader.terms(new 
Term("FIELD-NAME-HERE", ""));
 
                    while ("FIELD-NAME-HERE".equals( 
terms.term().field()))
                    {
                     // ... collect enum.term().text() ...
                String term = terms.term().text();
                        System.out.println(term);
                     if (!terms.next())
                            break;
                    }
                    terms.close();
                }



Thanks, and I hope this isn't a crazy question-
