| * Necessary classes to implement query builders. |

| * <h2>Query Parser Builders</h2> |
| * <p> |
| * The package <tt>org.apache.lucene.queryParser.builders</tt> contains the interface that |
| * builders must implement, it also contain a utility {@link org.apache.lucene.queryparser.flexible.core.builders.QueryTreeBuilder}, which walks the tree |
| * and call the Builder for each node in the tree. |
| * Builder normally convert QueryNode Object into a Lucene Query Object, |
| * and normally it's a one-to-one mapping class. |
| * |
| * But other builders implementations can by written to convert QueryNode objects to other non lucene objects. |
