- All Implemented Interfaces:
- Serializable, Cloneable, RegexQueryCapable
public class RegexQuery
- extends MultiTermQuery
- implements RegexQueryCapable
Implements the regular expression term search query.

used by way of the RegexCapabilities
interface.

toString
public String toString(String field)
- Description copied from class:
Query
- Prints a query to a string, with
field
assumed to be the
default field and omitted.
The representation used is one that is supposed to be readable
by QueryParser
. However,
there are the following limitations:
- 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.
- Some of the more complicated queries (e.g. span queries)
don't have a representation that can be parsed by QueryParser.
- Specified by:
toString
in class Query
equals
public boolean equals(Object o)
- Overrides:
equals
in class MultiTermQuery
hashCode
public int hashCode()
- Overrides:
hashCode
in class MultiTermQuery
