java - Searching multiple fields with Lucene - Stack Overflow

MultiFieldQueryParser is what you want, as you say.

Make sure:

• The field names are always used consistently
• The same Analyzer is used on both fields, and also on the query parser
• You won't find partial words by default, so if you search for jack you won't find jackson. (You can search for jack* in that case.)

Regarding field name, I always set up an enum for my field names, then use e.g. MyFieldEnum.firstname.name() when passing field names to Lucene, so that if I make a spelling mistake the compiler can catch it, and it's also a good place to put Javadoc so you can see what the fields are for, and also a place where you can see the complete list of fields you wish to support in your Lucene documents.
