# Query behavior changes for application_url, title, and location filters

jobdataapi.com 4.18.22 / API version 1.21

### Multi-keyword queries removed for application_url

Support for multi-keyword ([mk]) queries on the application_url filter parameter has been removed effective immediately. As a result, queries using application_url as a filter parameter are no longer supported in multi-keyword mode on the following endpoints:

/api/jobs/ ([see docs](/c/jobs-api-endpoint-documentation/))

/api/jobsexpired/ ([see docs](/c/jobs-expired-api-endpoint-documentation/))

Single-value filtering on application_url remains unchanged. Any existing queries relying on [mk] behavior for this parameter should be updated accordingly.

### Minimum query length enforced for title and location

Queries using [the title= or location= filter parameters](/c/jobs-api-endpoint-documentation/) on the /api/jobs/ endpoint now require a minimum keyword length of 3 characters. This change is due to these filters operating on a trigram-based index. Any title or location query containing keywords shorter than 3 characters will be ignored, including when used in multi-keyword [mk] mode.

We recommend adjusting client-side validation or query builders to enforce this minimum length to avoid unexpected results.
