Abstract
In research, indicators are partial since each indicator is susceptible to methodological and technical problems that require both decisions by the indicator developer as well as corrections and modifications at researcher's level. Considering the different limitations, the question arises whether one can use research indicators in an efficient way forever. Given the fact that we now know quite a lot about the strengths and weaknesses of such indicators, it does not contradict their use, but an inexperienced handling of such indicators should be avoided.
