Relevance class
Provides information for manually tuning the relevance of a field in a search. When a query includes terms that match the field, the results are given a boost in the response based on these tuning parameters.
Constructors
Properties
- duration → String?
-
Specifies the time period that the boost applies to. For example, to make
the boost apply to documents with the field value within the last month, you
would use "2628000s". Once the field value is beyond the specified range,
the effect of the boost drops off. The higher the importance, the faster the
effect drops off. If you don't specify a value, the default is 3 months. The
value of the field is a numeric string followed by the character "s", for
example "86400s" for one day, or "604800s" for one week.
final
- freshness → bool?
-
Indicates that this field determines how "fresh" a document is. For example,
if document 1 was created on November 5, and document 2 was created on
October 31, document 1 is "fresher" than document 2. You can only set the
Freshness

fields.final - hashCode → int
-
The hash code for this object.

- importance → int?
-
The relative importance of the field in the search. Larger numbers provide
more of a boost than smaller numbers.
final
- rankOrder → Order?
-
Determines how values should be interpreted.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
-
valueImportanceMap
→ Map<
String, int> ? -
A list of values that should be given a different boost when they appear in
the result list. For example, if you are boosting a field called
"department," query terms that match the department field are boosted in the
result. However, you can add entries from the department field to boost
documents with those values higher.
