Potser podríeu intentar variants ortogràfiques:
communication case » communication channels, communication culture
euclidean dspaces » euclidean spaces, euclidean distances, euclidean subspaces
euclidean affine » euclidean polyaffine, euclidean steiner, euclidean plane
case it's » age it's, easy it's, else it's
it's code » it's done, it's more, isps code
dspaces » ddspaces
space » dspace

• Si vols fer servir operadors booleans, han d'estar en majúscules: communication case it's code ((((euclidean affine) OR (euclidean dspaces))) OR (euclidean space))~.
• Afegint truncament pot recuperar més registres: communication case it's code ((((euclidean affine) or (euclidean dspaces))) or (euclidean space))*.
