The method signature for a search in lucene is (in the easiest case) hits = search(query) where search is a method of a searcher object, and query is a query object. Basically there are two ways to create a query object: a) use the query parser b) construct it yourself Option a) allowes to formulate queries with the options described in http://jakarta.apache.org/lucene/docs/queryparsersyntax.html. For a single field a query might look like 'some term' with the field defined as the default field. To search other fields than the default field, you can use <fieldname>:term. To combine subqueries you can use logical operators like AND, OR... So a query might look like creator:Castro AND category:computer If you want to construct the query yourself you have to look at the API docs and the different types of query subclasses. E.g. you could combine two TermQuery objects with a BooleanQuery object.
