    441444Queries in ''Advanced Search'' `MUST` be performed using ''FCS-QL'' ([#REF_FCSQL FCS-QL]). The Endpoint `MUST` support parsing all of FCS-QL. If an Endpoint does not support a query, i.e. the used operators or layers are not supported by the Endpoint, it `MUST` return an appropriate error message using the appropriate SRU diagnostic ([#REF_LOC_DIAG LOC-DIAG]).

    463466'''NOTE''': Endpoints supporting ''Advanced Search'' `MUST` be able to parse all of FCS-QL. If they don't support a certain FCS-QL feature, they `MUST` generate an appropriate error message (see section [#sruCQL SRU/CQL]). If an Endpoint ''only'' supports ''Basic Search'', it `MUST NOT` silently accept queries that include FCS-QL features.\\
    464 '''NOTE''': FCS-QL layer identifiers are reserved. The Endpoint `MUST` prepend the local prefix '''x-''' to any identifier used outside of the reserved set, e.g., '''x-funky''' for a local identifier '''funky'''.
     467'''NOTE''': FCS-QL layer identifiers are reserved. The Endpoint `MUST` prepend the local prefix {{{x-}}} to any identifier used outside of the reserved set, e.g., {{{x-customLayer}}} for a local identifier {{{customLayer}}}.
