Text Extender: Administration and Programming


Summary of Changes

Structured document support has been added. Text Extender can recognize the structure of tagged documents, based on a document model that you provide. The supported tagged documents are XML, HTML, or tagged ASCII documents. The benefit of this feature is that a search can be restricted to a particular section or list of sections.

Linguistic support for Arabic, Hebrew and Russian has been added.

The number of supported CCSIDs has been extended. Documents in Unicode can now be indexed and searched.

For Windows NT users, an example of an administration and search interface is provided. The interface is in the form of a wizard that guides you through administration and search tasks. The Java source code is provided.

Enable text columns multiple times. This lets you enable text columns for more than one index type, or use different index options.

You can specify a table space for log tables.

A new administration command has been added for the reorganization of an index. This is offered in addition to the current automatic reorganization. Reorganization of indexes makes searching more efficient after an index has been updated many times.

Get Index Status now displays the status of primary and secondary indexes so that you can determine if manual reorganization of an index is necessary.

You can now compile an Ngram thesaurus using the new command TXTHESN. This command supplements TXTHESC which compiles a standard thesaurus.
