Job Search configurations
Factors that affect search results
Together, "Featured Job Search", "Enable Broadening", and "Disable Keyword Match" have a significant impact on the number and relevance of jobs returned to the job seeker. The most appropriate configuration of these three factors depends on your business needs. The best method for determining your optimal configuration is to apply different test scenarios and evaluate the outcomes during a testing phase.
Featured job search: Use featured job searches to assign promotional values to individual jobs. This allows you to highlight jobs that are important to your business needs. See the featured job search documentation for best practices and implementation details.
disableKeywordMatch: This parameter allows Job Search to return keyword-based matches to a job seeker's query in addition to relevant matches. The default setting is
false. Setting this parameter to
truedisables the keyword match, so fewer jobs (only those determined to be relevant by the ML feature) are returned.
enableBroadening: Use this parameter to expand the job seeker's query by relaxing their stated restrictions on location and job categories. The default setting is
false. Enabling this parameter increases the number of search results returned but may decrease the relevance of the overall results set to the job seeker.
Search configuration outcomes
To return only the most relevant jobs: Set
false. This improves the API's relevance-related
performance metrics since only the relevant jobs are returned. However, fewer
jobs overall are returned in the search results.
To return a higher number of jobs including both relevant and keyword matched
keyword-matched results are listed after the relevant jobs in the results.
Query expansion results are not returned.
To return a higher number of jobs including both relevant and query expanded
true. The job
seeker's query is expanded to include related job categories and nearby
locations. These additional jobs are listed after the relevant results.
Keyword-based matches are not returned.
To return the highest possible number of jobs: Set
true. Job Search returns the most relevant
jobs at the top of the search results, followed by keyword matched jobs and
query expanded jobs (by location, job category, and so on). This
maximizes the total number of jobs returned.

For best performance and to avoid latency, set up the results page to display 20 or fewer jobs at a time. See the search overview page for more information on implementing pagination.
customAttributes gives you the flexibility to assign additional values to your
jobs according to your business needs (for example, GPA scores) and use these
values to filter the results.
A detailed overview of the
location field can be found on the
location fields page.
Providing the job's street address instead of GPS coordinates in the
field helps Job Search improve location detection and search relevance.
regionCode field if a single company has multiple job openings in
different geographic regions. Assigning a
regionCode to each listing ensures
that a search query returns jobs only in the job seeker's desired location
rather than global results matching the search query. For example, a search
on the location keyword "Cambridge" without a
regionCode in place returns
results from both Cambridge, UK and Cambridge, MA, USA. This decreases search
These two fields allow Job Search to use localised search logic in different
geographic regions (for example, "lorry driver" in
en_GB as opposed to "truck
driver" in the United States). Set
to match the geographic location that the user is searching (such as the United
request.filters.language_code to the appropriate language code for
that region (
en_GB in this case).
This parameter sets a radius (in miles) around a job seeker's indicated
location. Job Search returns results inside this geographic range. How this
distance is applied to the geography of the search results depends on the type
of location information entered. If the job seeker enters a street address, the
radiusInMiles distance is set from a single point. If the job seeker enters a
city, Job Search applies a bounding box around the city limits and calculates
distance from the box edges. If the user enters only a state or country,
radiusInMiles is ignored.
Make sure that the mileage radius is as small as possible. Setting
the mileage to a larger range causes Job Search to return results that may be
outside the job seeker's desired location, decreasing relevance. For example,
searching for jobs in New York City with
radiusInMiles set to 100 miles
returns results in both New Jersey and Upstate New York. Keeping the radius as
small as possible increases the relevance of the results.
This parameter sets the length of time that the job posting remains active before it's removed from search results. By default, CTS removes jobs 30 days after the creation time (UTC time).
This is not a required field, however using
the relevance of the search results.
Job Search configurations: Custom ranking
Featured job search allows you to influence a user's search results by
highlighting jobs based on a single variable (
promotionValue). See the
featured job search
documentation for details.
Custom ranking allows you to influence search results based on multiple
variables, offering more granular control over the rankings. This feature is
useful in applications that require balancing relevance with economic interests,
such as a multi-tiered Cost-per-Click (CPC) subscriber system. Influence over
how jobs are ranked on top of the original relevance score is based on two
rankingExpression: This variable controls how jobs are ranked based on their calculated relevance scores. 'rankingExpression' must be set to 'filterable' in order for Job Search to index the parameter.
importanceLevel: This parameter sets the importance level of a job's ranking position when it's returned in search results. There are six possible levels: Unspecified,
EXTREME. Setting the value to
EXTREMEcauses all other API-generated relevance factors to be ignored, so use this value sparingly. Jobs set to
EXTREMEare returned at the top of the job seeker's query instead of the most relevant jobs.
Featured job search versus custom ranking: A featured job search is most useful for promoting a single category of jobs above the relevance ranking, for example jobs at a certain company. If you need to rank jobs according to multi-level CPC (Cost Per Click) variables in addition to the relevance ranking, custom ranking is a better choice.
Commute search allows job
seekers to search for jobs based on commute time. To enable it, include a
CommuteFilter object in the
JobQuery.commuteFilter field. The
CommuteFilter calculates commute time using a job seeker's indicated
commute method, travel duration, and start coordinates. Job seekers must also
departureTime to include in the time calculation. See the Commute Search
how-to pages for details.
Commute search results are based on historical and aggregated data rather
than live traffic conditions. The
departureTime traffic conditions are
calculated from average traffic conditions at the specified time of day. The
TRAFFIC_FREE options under
roadTraffic are average traffic
conditions at morning rush hour and midnight, respectively. Users receive the
same commute search results no matter what time of day they send a query.
Job Search supports tenants as a middle organizational layer between a Google Cloud Platform project and any data uploaded to it. Tenants prevent data from being shared across tenancy barriers, allowing you to isolate subsets of your data without the need for multiple projects. Multi-tenancy is useful in situations where you have multiple customers and don't want to share data between them, but would like to maintain a single GCP project for internal billing and reporting. For example:
- Job site providers building job sites for organizations with multiple subsidiary companies.
- Hiring agencies building applicant tracking systems for multiple businesses.
Each project is assigned a single default tenant ID. You can implement multi-tenancy by creating more than one tenant within a given project.
Tenants are fully isolated from one another. All APIs ask for only a single tenant to prevent data being queried across multiple tenants in the same API call. The machine learning algorithms similarly treat tenants as discrete units and do not cross tenancy barriers. A project can support as many tenants as required.
CTS provides very light tenant support. You are responsible for creating tenants, assigning tenant IDs, and providing the correct tenant ID when making a request. CTS verifies that the tenant ID is owned by a given project and retrieves data from the tenant provided. Any additional security to catch unauthorized access must be managed in your backend system.
Data management & error handling
Uploading jobs: Data issues can prevent jobs from being uploaded to Job Search. Please see the HTTP Response Codes page for a list of error codes. Common examples include:
- Job locations are incorrect, so the request can't be resolved.
- Company or Job fields do not exist, so a bad request is returned.
There are three main options for troubleshooting job uploading issues:
Indexing jobs: Job Search is designed to index all of your uploaded jobs within a set period of time. However, you may have quota restrictions on your end. Be sure to check your system for restrictions on indexing requests before sending jobs to CTS.
Self-inflicted DDoS attacks
API services provided over the internet can have intermittent connection failure, a prolonged outage, sudden service maintenance and other events that require a client application to retry the API request. Make sure to design the retry with network friendly behavior, for example exponential backoff.
Avoid sending traffic higher than your provisioned quota, especially far higher than your provisioned quota. Otherwise, your traffic may be classified as malicious and therefore blocked.
Duplicate jobs negatively impact a job seeker's search experience. Job Search includes two features to minimize duplicates:
Create jobs: If you try to create 2+ jobs with the following criteria, the record is rejected and a 4xx error is returned:
- same location/
Search for jobs: Job Search surfaces jobs that are relevant to job seeker's search query. A built-in feature of the relevance algorithm makes sure that any returned jobs are diversified, preventing nearly identical jobs from showing up next to each other in search results.
