Added

• Experimental facet and filter skill_cluster has been added for ranking and filtering job postings by skill clusters. A skill cluster is a grouping of skills that categorize a posting into a particular job type. Skill clusters are organic groupings of job types that can change over time, so they don't have concrete names (a skills cluster's name can be categorized as one of the top job titles for the cluster at a particular time), therefore skill cluster names are not provided as facets or filters.

2.3.0 (January 11)

Changed

• The skills taxonomy's search scoring process has been updated to incorporate search term relevance and approximate matches. This will allow more relevant search terms to appear at the top of search results. As a result, search score values and the order of search results will be different from the former search process.

December 2018

2.2.0 (December 19)

Added

• Added ids to the city taxonomy
  • The /taxonomies/city/lookup endpoint now works with cities
  • The /taxonomies/city endpoints now includes id values (previously they were null)
• Added a city filter that uses city ids
• Added a city facet that allows you to rank on city ids, this facet works on the following endpoints:
  • Rankings – /rankings/city
  • Nested rankings – /rankings/city/rankings/city
  • Ranking timeseries – /rankings/city/timeseries

Changed

• The city taxonomy has been updated to include ids. You can now search, list, and lookup cities just like you can with all of the other taxonomies, as well as filter and rank on city ids.

September 2018

2.1.0 (September 18)

Added

• Added an optional filter object for more expressive syntax.

  • include field specifies items to be included in the filter.
  • exclude field specifies items to be excluded from the filter.
  • include_op field allowing for matching any (or) or all (and) of the specified items in the include filter (Defaults to or if unspecified).

  JSON

  {
    "filter": {
        "when": {"start": "2018-01", "end": "2018-06"},
        "skills_name": {
            "include": ["Accounting", "Automation"],
            "exclude": ["Management"],
            "include_op": "and"
        }
    }
  }

Deprecated

• The skills_op filter. It has been replaced by the more flexible filter options detailed in the Added section.

Removed

• Both the source_broad and source_specific filters and facets have been removed.

July 2018

2.0.0 (July 25)

Added

• New metric: posting duration–a measure of how long a posting has been active–as a signal of how difficult it is to fill a specific position and insight into demand.
• New filter: experience level filtering to refine analysis of employer demand, e.g. 0-3 years (min_years_experience and max_years_experience).
• New filter: filtering postings by full-time positions versus part-time (employment_type).
• New response field: links to live job postings in /samples responses when available.
• New filter option: filtering by the month in which postings were posted or removed, not just months in which postings were active.

Changed

• New features are powered by improvements in the underlying data.
  • Improved de-duplication methodology.
  • An emphasis on jobs posted to employer sites.
  • Clearer sourcing information for active posting samples with linking.
• All job posting samples will be viewable, and as a result the /samples endpoint will no longer have a unique_postings_not_displayable key.
• The yearmonth field in responses to the /samples endpoint will be replaced by posted and expired dates.
• There will be a noticeable change in posting volume in comparison to our previous version—this is primarily caused by the data improvements.

Deprecated

• Both the source_broad and source_specific filters and facets will be removed.

Removed

• Due to methodology changes, job posting history prior to September 2016 will no longer be available. If you are already using the /meta endpoint correctly to get available posting months before pulling data, no change will be required. When the changes are released, the /meta response will reflect the new set of available months.
