LUCENE TO-DO ITEMS
|
||
|
||
|
||
- Term Vector support
|
||
c.f.
|
||
http://nagoya.apache.org/eyebrowse/ReadMsg?listName=lucene-dev@jakarta.apache.org&msgNo=273
|
||
http://nagoya.apache.org/eyebrowse/ReadMsg?listName=lucene-dev@jakarta.apache.org&msgNo=272
|
||
|
||
- Support for Search Term Highlighting
|
||
c.f.
|
||

|
||
http://nagoya.apache.org/eyebrowse/ReadMsg?listName=lucene-dev@jakarta.apache.org&msgId=115271
|
||
http://www.iq-computing.de/index.asp?menu=projekte-lucene-highlight
|
||
http://nagoya.apache.org/eyebrowse/BrowseList?listName=lucene-dev@jakarta.apache.org&by=thread&from=56403
|
||
|
||
- Better support for hits sorted by things other than score.
|
||
An easy, efficient case is to support results sorted by the order documents were
|
||
added to the index. A little harder and less efficient is support for
|
||
results sorted by an arbitrary field.
|
||
c.f.
|
||
http://nagoya.apache.org/eyebrowse/ReadMsg?listName=lucene-dev@jakarta.apache.org&msgId=114756
|
||
http://www.mail-archive.com/lucene-user@jakarta.apache.org/msg00228.html
|
||
|
||
- Add ability to "boost" individual documents/fields.
|
||
When a document is indexed, a numeric "boost" value could be specified for the whole
|
||
document, and/or for individual fields. This value would be multipled into
|
||
scores for hits on this document. This would facilitate the implementation of
|
||
things like Google's PageRank.
|
||
c.f.
|
||
http://nagoya.apache.org/eyebrowse/ReadMsg?listName=lucene-dev@jakarta.apache.org&msgId=114749
|
||
http://nagoya.apache.org/eyebrowse/ReadMsg?listName=lucene-dev@jakarta.apache.org&msgId=114757
|
||
|
||
- Add to FSDirectory the ability to disable the use of lock files altogether (for read-only media).
|
||
Status: COMPLETED
|
||
|
||
- Add some requested methods:
|
||
String[] Document.getValues(String fieldName);
|
||
String[] IndexReader.getIndexedFields();
|
||
void Token.setPositionIncrement(int);
|
||
c.f.

|
||
http://nagoya.apache.org/eyebrowse/ReadMsg?listName=lucene-dev@jakarta.apache.org&msgId=330009
|
||
|
||
- P<>ter Hal<61>csy's changes to the QueryParser that make it possible to
|
||
programmatically specify a default operator (OR or AND).
|
||
c.f.
|
||
http://nagoya.apache.org/eyebrowse/ReadMsg?listName=lucene-dev@jakarta.apache.org&msgId=115677
|
||
Status: COMPLETED
|
||
|
||
- The recenly submitted code that allows for queries such as
|
||
"Microsoft suc*" to match "Microsoft success" and "Microsoft sucks".
|
||
c.f.
|
||
http://nagoya.apache.org/eyebrowse/ReadMsg?listName=lucene-dev@jakarta.apache.org&msgId=333275
|
||
Status: COMPLETED
|
||
|
||
- Make package protected abstract methods of org.apache.lucene.search.Searcher
|
||
public (I'd like to be able to make subclasses of Searcher, IndexWriter, InderReader).
|
||
c.f.
|
||
http://www.mail-archive.com/cgi-bin/htsearch?method=and&format=short&config=lucene-dev_jakarta_apache_org&restrict=&exclude=&words=IndexAccessControl
|
||
Status: COMPLETED
|
||
|
||
- Add lastModified() method to Directory, FSDirectory and RamDirectory, so
|
||
it could be cached in IndexWriter/Searcher manager.
|
||
|
||
- Support for adding more than 1 term to the same position.
|
||
N.B. I think the Finnish lady already implemented this. It required some
|
||
pieces of Lucene to be modified. (OG).
|
||
|
||
- The ability to retrieve the number of occurences not only for a term
|
||
but also for a Phrase.
|
||
c.f.
|
||
http://www.mail-archive.com/lucene-dev@jakarta.apache.org/msg00101.html
|
||
|
||
- Alex Murzaku contributed some code for dealing with Russian.
|
||
c.f.
|
||
http://nagoya.apache.org/eyebrowse/ReadMsg?listName=lucene-dev@jakarta.apache.org&msgId=115631
|
||
|
||
- A lady from Finland submitted code for handling Finnish.
|
||
|
||
- Dutch stemmer, analyzer, etc.
|
||
c.f.
|
||
http://nagoya.apache.org/eyebrowse/ReadMsg?listName=lucene-dev@jakarta.apache.org&msgNo=145
|
||
|
||
- French stemmer, analyzer, etc.
|
||
c.f.
|
||
http://nagoya.apache.org/eyebrowse/BrowseList?listName=lucene-dev@jakarta.apache.org&by=thread&from=56256
|
||
|
||
- Che Dong's CJKTokenizer for Chinese, Japanese, and Korean.
|
||
c.f.
|
||
http://nagoya.apache.org/eyebrowse/ReadMsg?listName=lucene-dev@jakarta.apache.org&msgId=330905
|
||
|
||
- Selecting a language-specific analyzer according to a locale.
|
||
Now we rewrite parts of lucene codes in order to use another
|
||
analyzer. It will be useful to select analyzer without touching codes.
|
||
|
||
- Adding "-encoding" option and encoding-sensitive methods to tools.
|
||
Current tools needs minor changes on a Japanese (and other language)
|
||
environment: adding an "-encode" option and argument, useing
|
||
Reader/Writer classes instead of InputStream/OutputStream classes, etc.
