Krishna Keldec created LUCENE-5344:
--------------------------------------
Summary: StandardQueryParser ignores Default Operators
Key: LUCENE-5344
URL: https://issues.apache.org/jira/browse/LUCENE-5344
Project: Lucene - Core
Issue Type: Bug
Components: core/queryparser
Affects Versions: 4.5
Reporter: Krishna Keldec
AnalyzerQueryNodeProcessor ignores default operator when creating boolean query
clauses for overloaded tokens.
Classic query parser output: {{+content:a +content:320}}
{code:java}
QueryParser classicQueryParser;
classicQueryParser = new QueryParser(Version.LUCENE_45, "content", anaylzer);
classicQueryParser.setDefaultOperator(Operator.AND);
classicQueryParser.parse("a320"));
{code}
Flexible query parser output: {{content:a content:320}} *(ignores default
operator)*
{code:java}
StandardQueryParser flexibleQueryParser;
flexibleQueryParser = new StandardQueryParser(anaylzer);
flexibleQueryParser.setDefaultOperator(Operator.AND);
flexibleQueryParser.parse("a320", "content"));
{code}
The used analyzer:
{code:java}
Analyzer anaylzer = return new Analyzer() {
protected TokenStreamComponents createComponents(String field, Reader in) {
Tokenizer src = new WhitespaceTokenizer(Version.LUCENE_45, in);
TokenStream tok = new WordDelimiterFilter(src,
WordDelimiterFilter.SPLIT_ON_NUMERICS |
WordDelimiterFilter.GENERATE_WORD_PARTS |
WordDelimiterFilter.GENERATE_NUMBER_PARTS,
CharArraySet.EMPTY_SET);
return new TokenStreamComponents(src, tok);
};
{code}
