- **Customizable Scoring**: User boost, document frequency, and query frequency weighting

## Technology Stack

- **Java**: 21+ (configured via parent POM)
- **OpenSearch**: Latest (provided scope)
- **Apache Lucene**: Query parsing and text analysis
- **ICU4J**: Unicode text processing and normalization
- **JUnit 4**: Testing framework
- **Maven**: Build and dependency management

## Quick Start

    public static final String TEXT = "text";
    /** The prefix for reading fields. */
    public static final String READING_PREFIX = "reading_";
    /** The score field. */
    public static final String SCORE = "score";
    /** The query frequency field. */
    public static final String QUERY_FREQ = "queryFreq";
    /** The document frequency field. */
    public static final String DOC_FREQ = "docFreq";

 * <p>Usage example:</p>
 * <pre>
 * {@code
 * DefaultContentsParser parser = new DefaultContentsParser();
 * SuggestItem item = parser.parseSearchWords(words, readings, fields, tags, roles, score, readingConverter, normalizer, analyzer, langs);
 * }
 * </pre>
 *
 * @see ContentsParser
 * @see SuggestItem
 * @see ReadingConverter
 * @see Normalizer
 * @see SuggestAnalyzer
