Preface

When we enter keywords, we hope to support filtering multiple fields, so that the coverage of the search content will be larger.

The MultiFieldQueryParser class is mainly used to match multiple fields.

Single field search

QueryParser parser=new QueryParser("content",analyzer);
Query query =parser.parse(kw);

Multiple field search

String[] fields={"title","content"};
MultiFieldQueryParser parser=new MultiFieldQueryParser(fields,analyzer);

parser.parse(keywords,fields,analyzer);
