Fields

Lucene supports searching by several fields of an index. When performing a search, you can either specify a field or use the default field. The field names and default field are implementation-specific.

You can search any field by typing the field name followed by a colon : and then the term you are looking for.

As an example, let us assume a Lucene index contains two fields, title and text, and text is the default field. If you want to find the document entitled “Jakarta Project”, which contains the text “lucene”, you can enter:

title:"Jakarta Project" AND text:lucene

or

title:"Jakarta Project" AND lucene

Since text is the default field, the field indicator is not required.

Note

The field is only valid for the term that it directly precedes, so the query

title:Jakarta lucene

will only find “Jakarta” in the title field. It will find “lucene” in the default field (in this case the text field).
