    162162==== WHERE OPERATIONS ====
    163 The WHERE clause describes patterns that the solutions need to match. A set of operations are used to bind sets of RDF triples to unknown variables. Variables are specified using a "?" symbol, for example "?property". There are 4 different types of operations that may be performed in a WHERE clause: match statements, union statements, filter statements and optional statements. Note that WHERE clauses may be nested, and therefore it is possible to add additional WHERE clause operations from within a WHERE clause operation.
