org.apache.lucene.queryparser.flexible.core.nodes.NoTokenFoundQueryNode
- All Implemented Interfaces:
- Cloneable, QueryNode
public class NoTokenFoundQueryNode
- extends DeletedQueryNode
A NoTokenFoundQueryNode
is used if a term is convert into no tokens
by the tokenizer/lemmatizer/analyzer (null).
Method Summary |
QueryNode |
cloneTree()
Recursive clone the QueryNode tree The tags are not copied to the new tree
when you call the cloneTree() method |
CharSequence |
toQueryString(EscapeQuerySyntax escaper)
convert to a query string understood by the query parser |
String |
toString()
Every implementation of this class should return pseudo xml like this:
For FieldQueryNode: <field start='1' end='2' field='subject' text='foo'/> |
