Subject Re: HTMLStripReader, HTMLStripCharFilter
Date Mon, 26 Apr 2010 23:15:56 GMT
Thanks for the update!  I appreciate the hard work.

Perhaps someone can help me with the use of HTMLStripCharFilter...

I get an exception (3.1-dev) similar to the one reported here (2.9):

With the following code:

    Analyzer htmlStripAnalyzer = new ReusableAnalyzerBase() {
        protected TokenStreamComponents createComponents(
                final String fieldName, final Reader reader) {
            return new TokenStreamComponents(new StandardTokenizer(Version.LUCENE_30,
                    new HTMLStripCharFilter(CharReader.get(reader))));
    String content = reader.document(id, fieldSelector).get(field);
    TokenStream ts = htmlStripAnalyzer.tokenStream(field, new StringReader(content));
    String best = highlighter.getBestFragments(ts, content,
    OffsetAttribute off = ts.addAttribute(OffsetAttribute.class);
    ts.incrementToken(); Stream closed
        at org.apache.lucene.analysis.standard.StandardTokenizerImpl.zzRefill(
        at org.apache.lucene.analysis.standard.StandardTokenizerImpl.getNextToken(
        at org.apache.lucene.analysis.standard.StandardTokenizer.incrementToken(

Looking at the source, I wonder if Tokenizer should override reset():

  public void reset() throws IOException {
    if (input != null) input.reset(); // would reset CharReader, StringReader

Rest assured we are working on this... but it unfortunately won't happen
overnight. First of all, the development of Lucene and Solr was merged such
that there is now one team working on this stuff. This way, both Solr and
Lucene developers can maintain this stuff.

There is now the practical issue to combine all Lucene and Solr analyzers
(not just the two components listed on that issue) into one package that can
then be used by both Lucene and Solr users:
