Histogram (v3)

Cloud Talent Solution allows you to get a histogram representation of the number of jobs associated to a given search. A histogram search returns a count of all jobs that match a particular query, broken down by the requested searchType. For example, a histogram search could return the number of jobs per employment type (full-time, part-time, etc) that exist in Mountain View, CA. To define the dimensions and parameters of the histogram, follow this guide.

Histograms are generally run in parallel with a search call, using the same JobQuery and the same requestMetadata.

Request

The histogram can be obtained from the underlying search API. This is achieved by setting the histogramFacets on the search API and defining the filters of the request. Note that the histogram observes all the filters as defined in the search query. The following example illustrates the mechanism of retrieving a histogram,

Required fields

  • searchTypes is a list of categories for which to return counts. For example, specify EMPLOYMENT_TYPE to return a count of employment types, such as full-time or part-time. See SearchType for a detailed list of enums.

Optional fields

  • jobQuery is the job query to perform in this search. See Search Filters for more details. In this example, no query is applied.

  • requestMetadata contains information about the user initiating the search. See the RequestMetadata section of the job search page for more information.

  • enableBroadening loosens the restrictions on location and job category of the search request, in order to return more results. For example, if a request specified jobs within a 20 mile radius of a location, setting this flag to true may return jobs from outside of that radius. The following example does not include broadened results.

Examples

The following example returns the list of job counts across the COMPANY_ID and the customAttribute someFieldName1:

Relevance thresholding

Histogram requests do not use relevance thresholding. To ensure that the counts are consistent between a histogram search and an identical job search, disableKeywordMatch in the job search must be false.
