Word Indexing and SQL-92

Currently, there is no concept of a word index in SQL-92. Therefore, there is no implementation of the CONTAINS operator.

NOTE: SQL-92 clients are able to perform data maintenance on a record that contains a column indexed with a word index. The index information will be handled correctly for use by future 4GL queries.
