Class ConstantScoreRangeQuery
- Cloneable, Serializable
public class ConstantScoreRangeQuery
A range query that returns a constant score equal to it's boost for
all documents in the range.
It does not have an upper bound on the number of clauses covered in the range.
If an endpoint is null, it is said to be "open".
Either or both endpoints may be open. Open endpoints may not be exclusive
(you can't select all but the first or last term without explicitly specifying the term to exclude.)
ConstantScoreRangeQuery(String fieldName, String lowerVal, String upperVal, boolean includeLower, boolean includeUpper)
|
boolean | equals(Object o) - Returns true if
o is equal to this.
|
String | getField() - Returns the field name for this query
|
String | getLowerVal() - Returns the value of the lower endpoint of this range query, null if open ended
|
String | getUpperVal() - Returns the value of the upper endpoint of this range query, null if open ended
|

true if the lower endpoint is inclusive

true if the upper endpoint is inclusive

ConstantScoreRangeQuery
public ConstantScoreRangeQuery(String fieldName,
String lowerVal,
String upperVal,
boolean includeLower,
boolean includeUpper)
equals
public boolean equals(Object o)
Returns true if o
is equal to this.
getField
public String getField()
Returns the field name for this query
getLowerVal
public String getLowerVal()
Returns the value of the lower endpoint of this range query, null if open ended
getUpperVal
public String getUpperVal()
Returns the value of the upper endpoint of this range query, null if open ended
hashCode
public int hashCode()
Returns a hash code value for this object.
includesLower
public boolean includesLower()
Returns true
if the lower endpoint is inclusive
includesUpper
public boolean includesUpper()
Returns true
if the upper endpoint is inclusive
rewrite
public Query rewrite(IndexReader reader)
throws IOException
Expert: called to re-write queries into primitive queries. For example,
a PrefixQuery will be rewritten into a BooleanQuery that consists
of TermQuerys.
- rewrite in interface Query
toString
public String toString(String field)
Prints a user-readable version of this query.
- toString in interface Query
