{uml}uistmo." » {uml}istmo.", {uml}uismo."
{uml}isismo." » {uml}ismismo.", {uml}issismo.", {uml}isistmo."
{uml}ismo." » {uml}mismo.", {uml}sismo.", {uml}istmo."

• If you are trying to use Boolean operators, they must be ALL CAPS: "((multiling or multilingue) or multilingueues)(({uml}uistmo." OR {uml}isismo.") or {uml}ismo.")*.
• Removing quotes may allow a broader search: ((multiling or multilingue) or multilingueues)(({uml}uistmo. or {uml}isismo. ) or {uml}ismo. )*.
