| Necessary classes to implement query builders. |
| |
| ## Query Parser Builders |
| |
| The namespace <tt>Lucene.Net.QueryParsers.Core.Builders</tt> contains the interface that builders must implement, it also contain a utility <xref:Lucene.Net.QueryParsers.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. |
