In this presentation, the search for $\text{H}\rightarrow \text{c} \bar{\text{c}}$ performed by CMS with Run-2 data is described. \\So far, the Higgs couplings to third generation fermions and muons have been measured with a good precision, while the assessment of second generation quark and first generation fermions still represents a challenge at the major collider experiments, like CMS and ATLAS. Searches for $\text{H}\rightarrow \text{c} \bar{\text{c}}$ have been carried out by both ATLAS and CMS using data collected during Run-2 at the LHC. The best result was obtained by CMS, by exploiting the VH production mode, with the Higgs boson generated in association with a W or Z boson, which offers a good signal to QCD background discrimination. With this analysis, an upper limit of 14 times the value predicted by the standard model was set on the product of the VH production cross section times the $\text{H}\rightarrow \text{c} \bar{\text{c}}$ branching ratio.
