Bose-Einstein correlations between like-sign charged-particle pairs in \({\rm e}^ + {\rm e}^-\to {\rm W}^ + {\rm W}^-\) events recorded with the OPAL detector at LEP at centre-of-mass energies between 183 GeV and 209 GeV are studied. Recently proposed methods which allow direct searches for correlations in the data via distributions of test variables are used to investigate the presence of correlations between hadrons originating from different W bosons in \({\rm W}^ + {\rm W}^-\to {\rm q\bar{q}q\bar{q}}\) events. Within the statistics of the data sample no evidence for inter-WW Bose-Einstein correlations is obtained. The data are also compared with predictions of a recent implementation of Bose-Einstein correlation effects in the Monte Carlo model PYTHIA
