[jira] [Updated] (LUCENE-5344) Flexible StandardQueryParser behaves
differently than ClassicQueryParser
[ https://issues.apache.org/jira/browse/LUCENE-5344?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Krishna Keldec updated LUCENE-5344:
-----------------------------------
Description:
AnalyzerQueryNodeProcessor creates a BooleanQueryNode instead of a MultiPhraseQueryNode for some circumstances.
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}
was:
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}
Fix Version/s: (was: 4.6)
Summary: Flexible StandardQueryParser behaves differently than ClassicQueryParser (was: StandardQueryParser ignores Default Operators)
