Why api query is giving empty output when the entity is having special character in RHV

Issue

• While querying the storage/network information using RHEV-M api, it's giving empty return value even when the particular entity exist in the RHEV-M. For example, when the search value is a network name Test_Network, it will return empty value. However a network with name Test is giving output correctly. Anything without special character is providing info correctly. Also querying the root path (/networks) is providing the correct output and is correctly displaying all entities including the one with special characters.
