JPA [[https://github.com/bcvsolutions/CzechIdMng/blob/develop/Realization/backend/core/core-api/src/main/java/eu/bcvsolutions/idm/core/api/service/AbstractReadDtoService.java#L419|predicate]] has to be constructed for all supported filter properties. Predicate can be constructed two ways:
+  * by service - predicates are constructed in ''[[https://github.com/bcvsolutions/CzechIdMng/blob/develop/Realization/backend/core/core-api/src/main/java/eu/bcvsolutions/idm/core/api/service/AbstractReadDtoService.java#L326|AbstractReadDtoService#toPredicates]]'' method. This predicates are statically implemented and not overidable.
+  * **By registered filter builders** - A mechanism for dynamic registry and composing of filters has been developed in the application for searching the data in IdM (identities, roles, tree structure components, etc.). A new filter can be registered for existing REST services in any module. Filter builder can be registered by custom module and can override filter builder from other module (e.g. filter in custom module can override core filter behavior).

+When no filter implementation is found for given filter property, then ''FilterNotSupportedException'' will be thrown. Filter builders (predicates) and all added filter properties have to be registered (constructed). Check for filter property is properly implemented is evaluated two ways:
+  * By registered filter builders - filter key is used.
+  * By filter definition (dto), if filter predicate is defined directly in service. Filter dto can define properties as fields or constants (see ''DataFilter'' generalization). **Make sure all properties are defined in filter dto if services predicate is used** - is required for check filter is supported.
+Check for filter property is properly implemented can be turned off by [[..:..:..application_configuration:dev:backend#entity_filters|configuration]] (e.g. before filter registration will be fixed).

+Find managers' contracts by subordinate contract. Finding managers' contracts by tree structures and set guarantees. The manager contract is on an organizational structure component superordinate to a structure component of the subordinate's contract. The manager (guarantee) can also be configured directly to the subordinate contract.
+Filter parameters
+  * ''managersByContract'' - a key parameter; uuid of the subordinate contract for which the searched are managers' contracts
+  * ''includeGuarantees'' - True => it is being searched for managers' contracts by tree structures and by direct guarantees. False => only managers' contracts by tree structures.
+  * ''validContractManagers'' - an additional parameter; valid now or in future contracts. True => manager contracts of subordinate contract ended in the past will not be returned. False => manager contracts of subordinate contract ended in the past will be returned. All managers' contracts  otherwise.
