eq

public static IndexQueryCriterion eq(String field,
                                     Object val)

Equal To.

Parameters:

field - Index field to apply criterion.

val - Strict equality value.

Returns:

Criterion.

lt

public static IndexQueryCriterion lt(String field,
                                     Object val)

Less Than.

Please note that null is not a valid value for setting search boundaries. The result of executing this criterion will not contain NULL values for the specified field. To obtain NULL values of the specified field, use explicit eq(field, null) or in(field, null, ...) criteria.

Parameters:

field - Index field to apply criterion.

val - Exclusive upper bound.

Returns:

Criterion.

public static IndexQueryCriterion lte(String field,
                                      Object val)

Less Than or Equal To.

Please note that null is not a valid value for setting search boundaries. The result of executing this criterion will not contain NULL values for the specified field. To obtain NULL values of the specified field, use explicit eq(field, null) or in(field, null, ...) criteria.

Parameters:

field - Index field to apply criterion.

val - Inclusive upper bound.

Returns:

public static IndexQueryCriterion gt(String field,
                                     Object val)

Greater Than.

Please note that null is not a valid value for setting search boundaries. The result of executing this criterion will not contain NULL values for the specified field. To obtain NULL values of the specified field, use explicit eq(field, null) or in(field, null, ...) criteria.

Parameters:

field - Index field to apply criterion.

val - Exclusive lower bound.

Returns:

Criterion.

gte

public static IndexQueryCriterion gte(String field,
                                      Object val)

Greater Than or Equal To.
