First let me say - Awesome tool! Almost too easy to be true, but with
that being said....
Hi, I have read several articles and postings that indicate that the
Field.Keyword field should be searchable but it's not working for me,
until I change to Field.Text. Parts of the index and search code are
included below - mostly lifted from articles,etc, including Erik Hatches
article on java.net. I created a small KnowledgeBase web application
that contains a category field, which I want to be searchable.
Searching using a query string of category:Doc* or
category:Documentation does not find a hit unless I change the code to
add the category to the index as a Field.Text instead of Field.Keyword.
The field value is out there: I have verified this using the TermEnum
to list the term values for field category and Documentation is in the
list of values.
The intention is to provide a 'Advanced Search' page that allows the
user to search specific fields, like category, title and author instead
of always using the 'all' field.
What am I doing wrong??? Thanks in advance.
Index code:
public boolean index(ArticleFormBean article) throws IOException {
IndexWriter writer = new IndexWriter(indexDir, new StandardAnalyzer(),
false);
Document doc = new Document();
doc.add(Field.UnStored("content", article.getContent()));
doc.add(Field.Text("title", article.getTitle()));
doc.add(Field.Text("author", article.getAuthor()));
doc.add(Field.UnIndexed("articleId",
String.valueOf(article.getArticleId())));
doc.add(Field.Keyword("createdDate", article.getCreateDate()));
doc.add(Field.Keyword("modDate", article.getModDate()));
doc.add(Field.Keyword("category", article.getCategory()));
// create an 'all' field
StringBuffer sb = new StringBuffer(4000);
sb.append(article.getTitle()).append("
").append(article.getAuthor()).append(" ");
sb.append(article.getContent()).append("
").append(article.getCategory());
doc.add(Field.UnStored("all", sb.toString()));
writer.addDocument(doc);
writer.optimize();
writer.close();
return false;
}
Search code:
File indexDir = new File("c:/dev/java/kb/index");
Directory fsDir = FSDirectory.getDirectory(indexDir, false);
IndexSearcher is = new IndexSearcher(fsDir);
Query query = QueryParser.parse(q, "all", new
StandardAnalyzer());
Hits hits = is.search(query);
