The method to use to order the query results. By default, IDOL Content Component displays results in order of relevance. If several documents have the same relevance, IDOL Content Component orders them by the autn:docid (document ID) number.
You can use one of the following sorting options:
Off. Do not sort documents.
AutnRank. Sort documents by the value in their AutnRankType field. The document with the highest AutnRankType field value is listed first.
Cluster. Sort documents by decreasing cluster ID. To use this option, you must set Cluster to True.
Database. Sort documents by increasing database number. The database numbers are defined in the IDOL Content Component configuration file.
Date. Sort documents by their date (the date contained in the result DateType fields). The most recent document is listed first.
If several documents have the same date, IDOL Content Component orders them by the autn:docid (document ID) number (the highest autn:docid is listed first).
Distcartesian. Sort documents according to their distance from a point, specified in Cartesian coordinates (X/Y). When you set XMLMeta to True, the action returns the calculated distance in a <autn:fieldsortvalue> tag in the response. Use the following format:
&Sort=Distcartesian{coordX,coordY}:POSITION
where,
coordX is the specified x coordinate.
coordY is the specified y coordinate.
POSITION is either:
X:Y, where X is the document field that contains the X coordinates, and Y is the document field that contains the Y coordinates. These fields must be either GeospatialType or NumericType fields. You must specify the fields in the order X:Y.For example:
&Sort=Distcartesian{10,11}:X:Y
In this example, IDOL Content Component sorts documents according to their distance from the point (10,11). The position of a document in this example is contained in the fields X and Y, respectively.
Distspherical. Sort documents according to their distance from a point, specified in spherical coordinates (latitude and longitude). When you set XMLMeta to True, the action returns the calculated distance in a <autn:fieldsortvalue> tag in the response. Use the following format:
&Sort=Distspherical{lat,long}:LOCATION
where,
lat is the specified latitude. Specify latitude positions south of the equator as negative.
long is the specified longitude. Specify longitude positions west of the Greenwich Meridian as negative.
LOCATION is either:
Latfield:Longfield, where Latfield is the document field that contains the latitude, and Longfield is the document field that contains the longitude. These fields must be either GeospatialType or NumericType fields. You must specify the fields in the order latitude:longitude.For example:
&Sort=Distspherical{37.75,-122.4}:Location
In this example, IDOL Content Component sorts documents according to their distance from San Francisco (37.75N,122.4W). The latitude and longitude position of a document in this example is contained in the Location field.
DocIDDecreasing. Sort documents by autn:docid (document ID). The document with the highest autn:docid is listed first.
DocIDIncreasing. Sort documents by autn:docid (document ID). The document with the lowest autn:docid is listed first.
fieldName:sortMethod. Sort results according to the value of a specified field.
NOTE: Documents in which the specified field is empty do not return.
This sort option is optimized when fieldName is a MatchType field.
fieldName. The name of the IDOL Content Component field to use to determine the document order. You can use fields that you create by using the UserMetaFields parameter.
sortMethod. The sorting method to apply to the field fieldName. The following sorting methods are available:
alphabetical

reversealphabetical
|
Sort documents by the reverse alphabetical order of the value in the NOTE: IDOL Content Component can perform the sorting process more quickly if |
Random. Sort documents randomly.
Relevance. Sort documents by their relevance (the document with the highest relevance is listed first).
If several documents have the same relevance, IDOL Content Component orders them by the autn:docid (document ID) number (the highest autn:docid is listed first).
ReverseDate. Sort documents by their date (the date contained in the DateType field). The oldest document is listed first.
If several documents have the same date, IDOL Content Component orders them by the autn:docid (document ID) number (the highest autn:docid is listed first).
ReverseRelevance. Sort documents in reverse order of relevance (the document with the lowest relevance is listed first).
If several documents have the same relevance, IDOL Content Component orders them by the autn:docid (document ID) number (the lowest autn:docid is listed first).
If you want to sort results by several criteria, specify these criteria in order of precedence, as follows:
sortOption1+sortOption2+...
NOTE: if you set Cluster as one of multiple sorting options, it automatically takes precedence over the other sorting options, regardless of its position in the list.
For example:
&Sort=Relevance+DRETITLE:alphabetical+Date
In this example, results order first by Relevance, then alphabetically by DRETITLE, and finally by Date.
