Isomorphic DataSources provide an advanced filtering mechanism for searching data, including a wide range of builtin search-operators, which allow searching via simple comparisons like equals and contains and more complex checks, like equalsOtherField and regex. You can also add entirely custom search-operators, via DataSource method addSearchOperator().

For a full list of operators, see OperatorId.
