IDOL Content Component 24.3

# FlattenIndexType

The hierarchical fields with this property are indexed as one level. When IDOL Server indexes one of the associated PropertyFieldCSVs, it indexes all subfields in the specified `FlattenIndexType` field as part of the parent field.

For example, if you configure `*/subject` as `FlattenIndexType`, and index the following XML:

    <documents>
       <article id="_21498602">
          <url>http://example.com/21490.html</url>
          <hltext_display>The history of pharmacogenetics </hltext_display>
          <source>Science Online</source>
          <media_type>text</media_type>
          <subject>
             <text>The prologue to pharmacogenetics began to play out around 1850 and spanned some 60 years into the 1900s.</text>
             <text>In 1953, the molecular basis of heredity, the double helix of DNA, was described.</text>
          </subject>
       <valid_time>Jul 13 2001 5:00AM</valid_time>
       </article>
    </documents>

IDOL Server indexes the `subject` field, and the contents of the two `text` subfields as the content of the `subject` field.

If you now query for a particular term in the `subject` field that is actually contained in a level below the `subject` field, for example the term pharmacogenetics, this document returns. If you did not flatten the `subject` field, the query would not return the document, because the `subject` field itself does not contain this term.

NOTE: You must configure any fields that you set as `FlattenIndexType` to also be Index fields.

For example, if you configure `*/subject` as `FlattenIndexType`, you must configure `*/subject` and `*/subject/*` with the Index property.

Type: | Boolean
Default: | False
Required: | No
Configuration Section: | `MyProperty`
Example: | `FlattenIndexType=True`
See Also: | Property PropertyFieldCSVs

NOTE: If you change this setting after you have indexed content into IDOL Server, you must reindex the content.
