Histogramme

Cloud Talent Solution vous permet d'obtenir une représentation sous forme d'histogramme du nombre de postes associés à une recherche donnée. Une recherche dans l'histogramme renvoie le nombre total d'offres d'emplois correspondant à une requête donnée, réparties en fonction du type de recherche (SearchMode) demandé. Par exemple, une recherche dans l'histogramme peut renvoyer le nombre d'emplois existants à Mountain View, Californie, par type de contrat (temps plein, temps partiel, etc.).

Les histogrammes sont généralement exécutés parallèlement à un appel de recherche, au moyen des mêmes paramètres JobQuery et requestMetadata.

L'histogramme est défini par le champ histogramQuery, une expression de chaîne unique. Pour en savoir plus sur les fonctions disponibles pour les requêtes d'histogramme, consultez la documentation sur histogramQuery.

Récupérer un histogramme

L'exemple de code suivant renvoie les résultats de l'histogramme :

Seuil de pertinence

Les requêtes d'histogramme n'utilisent pas de seuil de pertinence. Pour assurer la cohérence des décomptes entre une recherche d'histogramme et une recherche d'emploi identique, le champ disableKeywordMatch dans la recherche d'emploi doit être défini sur la valeur false.
