I have long been meaning to publish an updated codebase for Lucene in  
Action compatible with Lucene 2.0.  I adjusted the code a while ago,  
but I haven't published it yet (and I think the plan is to wait until  
LIA2 is finished to do so).  I did make notes when I made these  
changes, and I'm pasting them below for all to benefit from.

Replace all BooleanQuery.add's, e.g.:

    -      subjectQuery.add(tq, false, false);
    +      subjectQuery.add(tq, BooleanClause.Occur.SHOULD);

Substitute RangeFilter for DateFilter usage, e.g.:

    -    DateFilter filter = new DateFilter("modified", jan1, dec31);
    +    RangeFilter filter = new RangeFilter("modified", jan1,  
dec31, true, true);

    NOTE: The dates are now String's generated by  
DateUtils.dateToString() and incompatible with DateField

Replace all Field.Keyword/UnStored/Text/UnIndexed with the enumerated  
types, e.g.:

    -      doc.add(Field.Keyword("animal", animal));
    +      doc.add(new Field("animal", animal, Field.Store.YES,  
Field.Index.UN_TOKENIZED));

Rename PhrasePrefixQuery -> MultiPhraseQuery

Use instance of QueryParser instead of static parse method, e.g.:

    -        Query query = QueryParser.parse(expression, "contents",  
analyzer);
    +        Query query = new QueryParser("contents", analyzer).parse
(expression)

QueryParser subclasses adjusted for overridden getXXXQuery method  
signatures.

IndexReader.delete() updated to be  
IndexReader.deleteDocument/.deleteDocuments()

IndexWriter internal configuration values now accessed through  
getters/setters rather than the fields directly, with minMergeDocs  
renamed as setMaxBufferedDocs().

QueryParser.setLowercaseWildcardTerms() replaced  
with .setLowercaseExpandedTerms()

QueryParser.getRangeQuery() still uses DateField when constructing a  
RangeQuery.
   If your index is built using DateTools, you will need to subclass  
and override, as shown in QueryParserTest.testRangeQuery().
