public class SearchContentField
extends Object
implements Cloneable, Serializable

Field of a SearchContent object. It represents a piece of the information to be indexed that has name, value and the following indexing properties:

• indexed: true means that the field is searchable and must be used to match its owner SearchContent when a search query runs.
• stored: true means that the field must be stored in some way that allow it to be retrieved when a search query matches the owner SearchContent.
• tokenized: true means that the field can be optimized and changed before it is indexed. Usually a indexing tokenization consists in cleaning whitespaces, removing stop words, normalizing character casing among other optimization operations.

There are the following predefined fields, that are characterized by their names and have predefined special meaning to the search context:

Field	Description	Field name
Identifier	Identifier of the content being indexed. It can be used later to retrieve the content from search index. This field is indexed, stored and not tokenized.	FIELDNAME_ID
Title	Title of the content being indexed. Usually is used as the name of the hyperlink in a search results interface. This field is stored, not indexed and not tokenized.	FIELDNAME_TITLE
Subtitle	Subtitle of the content being indexed. Usually is presented close to the hyperlink in a search results interface, to present additional information of the content. This field is stored, not indexed and not tokenized.	FIELDNAME_SUBTITLE
URL	URL of the content being indexed. Usually is used as the URL of the hyperlink in a search results interface, consisting in an URL that allows the navigation to the content details. This field is stored, not indexed and not tokenized.	FIELDNAME_URL
Text	The textual searchable content. This is the only field used by search engines to search for contents based on provided search criteria. This field is indexed, tokenized and not stored.	FIELDNAME_TEXT

All information provided in fields is stored by the search engine and retrieved in search results in SearchHit objects.

Any field that does not match any of the above predefined field is considered a custom field and will have implementation-specific meaning and behavior.
