Indices are a powerful tool to analyse the dynamics of supersymmetric field theories; for instance, supersymmetric indices for non-conformal susy field theories can be used to explore their RG flows. An interesting class of indices can be defined by placing (non conformal) supersymmetric field theories on S^dxS^1 preserving susy. For N=1 this index is related to the N=1 superconformal index in a simple way. For N=2 superconformal theories one can also define an index but its extension to non conformal N=2 field theories is not possible. Nevertheless, I will show that a particular limit of the N=2 superconformal index, the "Schur limit", can be defined for non conformal field theories. I will then explore the properties and uses of this index.
