Hi,
I created an index of around 45000 documents. I search using Title and
Abstract field. (Using lucene 2.4.1)
When I look in lukeall, some titles are available in index, but I dont get
them when I search using title as keyword.
I have copied code snapshots below.
Recently we upgraded from lucene 2.0 to 2.4.1 and I am fairly new to
lucene. Please let me know what could be the possible issue.
IndexWriter writer = new IndexWriter(directory, new StandardAnalyzer(),
pCreate,
IndexWriter.MaxFieldLength.UNLIMITED);
........................
SimpleAnalyzer cjkAnalyzer = new SimpleAnalyzer();
doc.add(new Field(LuceneDocument.TITLE_FIELD, pTitle, Field.Store.YES,
Field.Index.ANALYZED_NO_NORMS));
doc.add(new Field(LuceneDocument.ABSTRACT_FIELD, pDescription,
Field.Store.YES, Field.Index.
ANALYZED_NO_NORMS));
...............
if (localeStr.equals("zh_CN") || localeStr.equals("ko_KR")) {
writer.addDocument(doc, cjkAnalyzer);
} else {
writer.addDocument(doc);
}
While searching the index, I use the analyser as below.
// construct the proper analyzer based on locale
if (pLocale.equals("zh_CN") || pLocale.equals(
"ko_KR")) { /* NOI18N */
analyzer = new SimpleAnalyzer();
} else {
analyzer = new StandardAnalyzer();
}
// analyze the keywords
ts = analyzer.tokenStream("abstract",
//$NON-NLS-1$
new StringReader(sb.toString()));
tokens = new ArrayList();
try {
while (true) {
Token token = ts.next();
if (token == null) {
break;
}
tokens.add(token.termText());
}
} catch (IOException ex) {
Logger.logException(Logger.TYPE_ERR, this,
"analyzeKeywords", ex);
//$NON-NLS-1$
}
// Loop through the keywords
for (int i = 0; i < tokens.length; i++) {
// Each keyword must be queried
against the title and abstract.
BooleanQuery bQuery = new
BooleanQuery();
TermQuery titleTerm = new
TermQuery(
new Term("title",
tokens[i])); //$NON-NLS-1$
TermQuery abstractTerm = new
TermQuery(new Term(
"abstract",
tokens[i])); //$NON-NLS-1$
if (keywordStatusListSize > i
&& ((Boolean)
keywordStatusList.get(i)).booleanValue()) {
bQuery.add(titleTerm,
BooleanClause.Occur.MUST);
bQuery.add(abstractTerm,
BooleanClause.Occur.MUST);
} else {
bQuery.add(titleTerm,
BooleanClause.Occur.SHOULD);
bQuery.add(abstractTerm,
BooleanClause.Occur.SHOULD);
}
if (flag || ((Boolean)
keywordStatusList.get(i)).booleanValue()) {
keyQuery.add(bQuery,
BooleanClause.Occur.MUST);
} else {
keyQuery.add(bQuery,
BooleanClause.Occur.SHOULD);
}
}
................................
CachingWrapperFilter cf;
Searcher searcher;
HitCollector collector;
................. some assignments...............
searcher.search(keyQuery, cf, collector);
Thanks & Regards,
Priya
