Managing Indexes

This article describes how to update and delete existing indexes within the Indexing Module.

24. Refresh – Click the Refresh button to refresh the Indexing tab to show the current counts.

25. Project Indexes – To delete or update an Index, select the checkbox next to the Index(s) and choose the applicable button in the Indexing Ribbon. The Project Indexes table contains the following values:

    • Index ID – The ID of the Index within the project.

    • Index Status – The status of the Index. If the Index Status is ERRORED, the Index should be deleted and a new Index should be built for the applicable scope(s).

    • Index Scope -- The content selected in generating the Index, either PROJECT, IMPORTS or SELECTIVE SETS.

    • Index Type – There are two different Index Types of EXTRACTED TEXT and OCR. While both extracted text and OCR text can be added to the dtSearch Index and be made searchable, this is done through different process, thus they are separated as different Index Types.

    • Actual Count – This is the actual number of items added to the dtSearch Index. If Actual Count does not equal Expected Count, the Index should be deleted, and a new Index should be built for the applicable scope(s).

    • Expected Count – This is the expected number of items that should be added to the dtSearch Index. If Actual Count does not equal Expected Count, the Index should be deleted, and a new Index should be built for the applicable scope(s).

    • Fragmentation – Fragmentation of an Index increases the size of the Index and slows searching, but the effect is generally not noticeable unless the fragmentation is severe. If the fragmentation of an Index is high and search results are taking a long time to complete, the Index should be deleted and a new Index should be built for the applicable scope(s).

    • Job ID – The Distributed Job ID of the Index.

26. Delete Index – To delete an Index from the project select the checkbox next to the Index, and click the Delete Index button. Any file(s) deleted from the Index may be part of a future Index Scope and will be available for indexing. Note that null indexes from the prior illustration (having 0 documents to index) have been deleted here.

27. Update Index Properties – To update Actual Count and Fragmentation to the most current states for one or more Indexes, select the Index(es) and click the Update Index Properties button.
