All Implemented Interfaces:
  `Accountable`

public class TermRangeQuery extends AutomatonQuery
A Query that matches documents within an range of terms.

This query matches the documents looking for terms that fall into the supplied range according to `BytesRef.compareTo(BytesRef)`.

NOTE: `TermRangeQuery` performs significantly slower than `point-based ranges` as it needs to visit all terms that match the range and merges their matches.

This query uses the `MultiTermQuery.CONSTANT_SCORE_BLENDED_REWRITE` rewrite method.

Since:
  2.9

## Constructor Details

### TermRangeQuery

public TermRangeQuery(String field, BytesRef lowerTerm, BytesRef upperTerm, boolean includeLower, boolean includeUpper)
Constructs a query selecting all terms greater/equal than `lowerTerm` but less/equal than `upperTerm`.

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.)

Parameters:
  `field` - The field that holds both lower and upper terms.
  `lowerTerm` - The term text at the lower end of the range
  `upperTerm` - The term text at the upper end of the range
  `includeLower` - If true, the `lowerTerm` is included in the range.
  `includeUpper` - If true, the `upperTerm` is included in the range.

### TermRangeQuery

public TermRangeQuery(String field, BytesRef lowerTerm, BytesRef upperTerm, boolean includeLower, boolean includeUpper, MultiTermQuery.RewriteMethod rewriteMethod)
Constructs a query selecting all terms greater/equal than `lowerTerm` but less/equal than `upperTerm`.

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.)

Parameters:
  `field` - The field that holds both lower and upper terms.
  `lowerTerm` - The term text at the lower end of the range
  `upperTerm` - The term text at the upper end of the range
  `includeLower` - If true, the `lowerTerm` is included in the range.
  `includeUpper` - If true, the `upperTerm` is included in the range.
  `rewriteMethod` - the rewrite method to use when building the final query

## Method Details

### toAutomaton

public static Automaton toAutomaton(BytesRef lowerTerm, BytesRef upperTerm, boolean includeLower, boolean includeUpper)

### newStringRange

public static TermRangeQuery newStringRange(String field, String lowerTerm, String upperTerm, boolean includeLower, boolean includeUpper)
Factory that creates a new TermRangeQuery using Strings for term text.

### newStringRange

public static TermRangeQuery newStringRange(String field, String lowerTerm, String upperTerm, boolean includeLower, boolean includeUpper, MultiTermQuery.RewriteMethod rewriteMethod)
Factory that creates a new TermRangeQuery using Strings for term text.

### getLowerTerm

public BytesRef getLowerTerm()
Returns the lower value of this range query

### getUpperTerm

public BytesRef getUpperTerm()
Returns the upper value of this range query

### includesLower

public boolean includesLower()
Returns `true` if the lower endpoint is inclusive

### includesUpper

public boolean includesUpper()
Returns `true` if the upper endpoint is inclusive

### toString

public String toString(String field)
Prints a user-readable version of this query.

Overrides:
  `toString` in class `AutomatonQuery`

### hashCode

public int hashCode()
Description copied from class: `Query`
Override and implement query hash code properly in a subclass. This is required so that `QueryCache` works properly.

Overrides:
  `hashCode` in class `AutomatonQuery`
See Also:
  - `Query.equals(Object)`

### equals

public boolean equals(Object obj)
Description copied from class: `Query`
Override and implement query instance equivalence properly in a subclass. This is required so that `QueryCache` works properly.

Typically a query will be equal to another only if it's an instance of the same class and its document-filtering properties are identical to those of the other instance. Utility methods are provided for certain repetitive code.

Overrides:
  `equals` in class `AutomatonQuery`
See Also:
  - `Query.sameClassAs(Object)`
  - `Query.classHash()`
