Overview
When passing Relevance as input to an Aws::Client method, you can use a vanilla Hash:
{
freshness: false,
importance: 1,
duration: "Duration",
rank_order: "ASCENDING", # accepts ASCENDING, DESCENDING
value_importance_map: {
"ValueImportanceMapKey" => 1,
},
}
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.
Returned by:
Instance Attribute Summary collapse
-
#duration ⇒ String
Specifies the time period that the boost applies to.
-
#freshness ⇒ Boolean
Indicates that this field determines how \"fresh\" a document is.
-
#importance ⇒ Integer
The relative importance of the field in the search.
-
#rank_order ⇒ String
Determines how values should be interpreted.
-
#value_importance_map ⇒ Hash<String,Integer>
A list of values that should be given a different boost when they appear in the result list.
Instance Attribute Details
#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.
Only applies to DATE
fields.
#freshness ⇒ Boolean
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
field on one DATE
type field. Only
applies to DATE
fields.
#importance ⇒ Integer
The relative importance of the field in the search. Larger numbers provide more of a boost than smaller numbers.
#rank_order ⇒ String
Determines how values should be interpreted.
When the RankOrder
field is ASCENDING
, higher numbers are better.
For example, a document with a rating score of 10 is higher ranking than
a document with a rating score of 1.
When the RankOrder
field is DESCENDING
, lower numbers are better.
For example, in a task tracking application, a priority 1 task is more
important than a priority 5 task.
Only applies to LONG
and DOUBLE
fields.
Possible values:
- ASCENDING
- DESCENDING
#value_importance_map ⇒ Hash<String,Integer>
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.
For example, you can add entries to the map with names of departments. If you add \"HR\",5 and \"Legal\",3 those departments are given special attention when they appear in the metadata of a document. When those terms appear they are given the specified importance instead of the regular importance for the boost.
