In Texis vesrion 7, Metamorph indexes are easier to update by using the new ALTER INDEX syntax, which avoids the need to specify the complete table and fields. For example:
ALTER INDEX searchIndex OPTIMIZE;
is equivalent to:
CREATE METAMORPH INDEX searchIndex
ON searchTable(Title\Meta\Body,Price,Count);
(assuming searchIndex already exists). Search the online Texis manual for "ALTER INDEX" for details.
