| <p>Prints a query to a string, with <code>field</code> assumed to be the default field and omitted. The representation used is one that is supposed to be readable by <a class="el" href="class_lucene_1_1_net_1_1_query_parsers_1_1_query_parser.html">QueryParser</a>. However, there are the following limitations: </p> |
| <ul> |
| <li> |
| If the query was created by the parser, the printed representation may not be exactly what was parsed. For example, characters that need to be escaped will be represented without the required backslash. </li> |
| <li> |
| Some of the more complicated queries (e.g. span queries) don't have a representation that can be parsed by QueryParser. </li> |
