How to convert TermDocs and TermEnum ??
Posted by "A. Lotfi" <ma...@yahoo.com>.
Hi,
I found some difficulties converting from old API to the newest one :
import org.apache.lucene.index.TermDocs; // does not exist
import org.apache.lucene.index.TermEnum; // does not exist
I tried the migration doc, but could not figure it out, here my code :
private List<Short>[] loadFieldValues(IndexReader reader) throws IOException {
List<Short>[] retArray = new List[reader.maxDoc()];
TermEnum termEnum = reader.terms (new Term (GEO_LOC));
try {
do {
Term term = termEnum.term();
if (term==null || term.field() != GEO_LOC) break;
TermDocs td = reader.termDocs(term);
String value = term.text();
.......
...........
td.close();
} while (termEnum.next());
} finally {
termEnum.close();
}
return retArray;
}
I will appreciate your help.
thanks
Re: DocsEnum <--- IndexReader.?

Hmm MIGRATE is supposed to cover this ... try searching in
MIGRATE.html for "How you obtain the enums has changed"?

DocsEnum <--- IndexReader.?
Posted by "A. Lotfi" <ma...@yahoo.com>.
Hi,
I am trying to migrate some code from version 2.9.0 to 4.2.1, I have this method :
public DocIdSet getDocIdSet(IndexReader reader) throws IOException {
OpenBitSet result = new OpenBitSet(reader.maxDoc());
TermDocs td = reader.termDocs(); <----- This line has error
try {
td.seek(term);
int[] arr = new int[BUFFER_SIZE];
int[] freq = new int[BUFFER_SIZE];
for (;;) {
int num = td.read(arr, freq);
if (num == 0)
break;
for (int j = 0; j < num; j++) {
result.fastSet(arr[j]);
}
}
} finally {
td.close();
}
return result;
}
The line that has error said :
The method termDocs() is undefined for the type IndexReader
I found this doc about migrating :
http://lucene.apache.org/core/4_0_0/MIGRATE.html
But IndexReader does not have a method that return the new class DocsEnum ( that renamed TermDocs).
Thanks, your help is appreciated.

BufferedTokenStream @Deprecated
Posted by "A. Lotfi" <ma...@yahoo.com>.
Hi,
I was told to migrate an old Lucene project from version :
2.9.1 to 4.2.1
As soon as I changed the jars, I got lot of errors , one of them :
The import org.apache.solr.analysis.BufferedTokenStream cannot be resolved
for this line :
import org.apache.solr.analysis.BufferedTokenStream;
in the new API it said :
@Deprecated public abstract class BufferedTokenStream extends TokenFilter
BufferedTokenStream used to have a method called read().
Can you please help me on how to fix this problem ?
Thanks, your help is appreciated.

Posted by "A. Lotfi" <ma...@yahoo.com>.
Hi,
I am new here trying to learn Lucence, I went to this page :
http://lucene.apache.org/core/3_6_1/api/core/index.html
In the bottom of the page it said :
To demonstrate these, try something like:
> java -cp lucene.jar:lucene-demo.jar:lucene-analyzers-common.jar org.apache.lucene.demo.IndexFiles rec.food.recipes/soups
>adding rec.food.recipes/soups/abalone-chowder
> [ ... ]
>> java -cp lucene.jar:lucene-demo.jar:lucene-analyzers-common.jar org.apache.lucene.demo.SearchFiles
I downloaded Lucence 3.6, don't know where to do the above demo.
Thanks, your help is appreciated.
