Custom Fields Flavor Index Configuration

The Custom Fields flavor is a special index flavor that allows you to use and create more custom fields in your documents.

Index Size

The Custom Fields flavor supports a maximum of 2.5GB of index data.

The querytextindex and findsimilar APIs can return a maximum of 10000 documents in the results.

You can create up to 15 custom index fields, 10 parametric fields, 10 numeric fields, and three expire date fields.

Standard Fields

The Custom_Fields flavor supports the same standard fields as the Standard Flavor.

For information about the field types, see Index Field Types.

Note: Field names in Haven OnDemand are not case sensitive. For example, the TITLE field name is equivalent to Title or title.

1 These fields are considered highly relevant indicators of document context. A match in these fields increases the relevance score for the result.

2 TITLE is a special field that is always returned at the top of document alongside the reference.

3 ROOTPARENT_<field> is a standard convention used to include information from a containing document that is relevant to a child document. For example, ROOTPARENT_FROM might contain the FROM field of the parent email for an attachment (where the attachment is indexed independently).

4 NORMALIZED_<field> is a standard convention used to indicate the normalized form of a field value.

Non-Standard Fields

You can configure custom fields with special types for your text indexes by using the Create Text Index API, or by using the Create Text Index option on the Text Indexes Account page. You must create the custom fields when you create the text index; you cannot change this configuration afterwards. The custom fields behave the same as standard fields with the same property, and you can use these fields for search and filtering. You can also create expire date fields, which allow you to define a date in the document after which the document is deleted. For more information, see Index Field Types

Haven OnDemand also stores any other non-standard fields in your documents. You cannot use these fields for retrieval, but you can display them in results by using the Print API parameter.
