Lucene BooleanQuery

Question

How to use booleanQuery with StandardAnalyzer in Lucene search?

Answer 1

I assume you mean parsing boolean queries using the QueryParser object, right? Lucene query syntax documentation should have everything you need.

Answer 2

According to the document, logical queries should be created once by BooleanQuery.QueryBuilder, and then considered immutable. See BooleanQuery.Builder.add (org.apache.lucene.search.BooleanClause)

http://programtalk.com/java-api-usage-examples/org.apache.lucene.util.QueryBuilder/ :

public Query parse(Type type, String fieldName, Object value) throws IOException {
    final String field;
    MappedFieldType fieldType = context.fieldMapper(fieldName);
    if (fieldType != null) {
        field = fieldType.name();
    } else {
        field = fieldName;
    }
    /*
     * If the user forced an analyzer we really don't care if they are
     * searching a type that wants term queries to be used with query string
     * because the QueryBuilder will take care of it. If they haven't forced
     * an analyzer then types like NumberFieldType that want terms with
     * query string will blow up because their analyzer isn't capable of
     * passing through QueryBuilder.
     */
    boolean noForcedAnalyzer = this.analyzer == null;
    if (fieldType != null && fieldType.tokenized() == false && noForcedAnalyzer) {
        return blendTermQuery(new Term(fieldName, value.toString()), fieldType);
    }
    Analyzer analyzer = getAnalyzer(fieldType);
    assert analyzer != null;
    MatchQueryBuilder builder = new MatchQueryBuilder(analyzer, fieldType);
    builder.setEnablePositionIncrements(this.enablePositionIncrements);
    Query query = null;
    switch(type) {
        case BOOLEAN:
            if (commonTermsCutoff == null) {
                query = builder.createBooleanQuery(field, value.toString(), occur);
            } else {
                query = builder.createCommonTermsQuery(field, value.toString(), occur, occur, commonTermsCutoff, fieldType);
            }
            break;
        case PHRASE:
            query = builder.createPhraseQuery(field, value.toString(), phraseSlop);
            break;
        case PHRASE_PREFIX:
            query = builder.createPhrasePrefixQuery(field, value.toString(), phraseSlop, maxExpansions);
            break;
        default:
            throw new IllegalStateException("No type found for [" + type + "]");
    }
    if (query == null) {
        return zeroTermsQuery();
    } else {
        return query;
    }
}

BooleanQuery. BooleanQuery- This is a container with Boolean sentences that are optional, mandatory, or forbidden subqueries. You can usually add a sentence to BooleanQueryusing an API method that looks like this:

public void add (Query request, boolean required, boolean prohibited)
