Activating Fast-Indexing

About this task

Fast-indexing is activated by specifying the list of content names (and types) in the fast-index option on a search collection's Indexing tab. The Fast-index memory usage details section of the Live Status > Indexing page for any live index in the Watson™ Explorer Engine administration tool provides information about how much RAM each fast-indexed content is using.

To activate fast-indexing:

Procedure

Select the Configuration tab for the search collection that contains the content elements that you want to fast-index.
Select the Indexing sub-tab.
To the right of the Global Settings header, click edit.
For the Fast Index field, select the Modified radio button, and enter the name of each content element that you want to fast-index in the box. Each entry should be on its own line and be of the format name|type. For example, if you have a field named year, the format would be year|int.

If data in the specified field is not of the type that is specified here (such as a content whose type is specified as "int" but contains the string "12x"), a message will be generated in the URL log and the value will not be fast-indexed.

Any type can be prefixed with checked- (for example, checked-date). A checked type will restrict the values that are fast-indexed to only those that the user has the right to view. This is useful if you are using content level security and not necessary if you are using document level security.

Results

Tip: If you are pushing contents to be indexed by Watson Explorer Engine using the Watson Explorer Engine API, you can fast-index individual content elements by adding the fast-index="type" attribute to those contents. You should replace type with the appropriate datatype. Supported datatypes are the types listed in Activating Fast-Indexing

When added in this manner, the fast-index information is stored in the index and identified as (transient) in the fast-index section of the Live Status tab.
