Search performance improvements

Improved the performance** of job searches and company searches by **up to 30x** when using some of the following filters:

  • company_name_partial_match_or
  • company_name_partial_match_not
  • company_location_pattern_or
  • company_description_pattern_or
  • company_description_pattern_not
  • job_title_pattern_or
  • job_title_pattern_not
  • job_location_pattern_not
  • job_description_pattern_not

This will have effect especially when passing large arrays of values in them (of 50+ elements). Queries that before would take ~50 seconds are now taking 2-3 seconds, according to our tests.

Improved extraction of matching phrases

Improved extraction of matching phrases

Before, when filtering jobs by keywords in job descriptions, matching_phrases and matching_words could be empty even when there were matches. We now extract the matching phrases and words from the job description.

URL domain filters

We've added new domain-based filters to both Jobs Search endpoint and Company Search endpoint:

New filters:

  • url_domain_or - Find jobs/companies from specific domains
  • url_domain_not - Exclude jobs/companies from specific domains

This allows you to target or exclude jobs from specific platforms like greenhouse.io, workable.com, linkedin.com, etc. Perfect for focusing on direct company postings or excluding certain job boards from your results.

Slow company searches are now 2-6x faster

Company searches that before took too long or were just impossible to run just take seconds. This would typically happen when adding job or technology filters to the search. Here are examples of such queries: - Companies using Snowflake, with a high confidence score in the usage of that technology, from the US. Now it completes in less than 5 seconds - Companies hiring data engineers in the US, UK or Canada. Now completes in 3-4 seconds as well

These and other slow queries are now 2-6x faster. These is how long queries would take before and after the improvement:

Time beforeTime nowImprovement
~16s~9s1.8x faster
~52s~13s4.0x faster
~98s~16s6.1x faster
Timeouts (at 2 mins)20-35s~6x faster

Stable company logo URLs

Previously, when scraping new jobs, we stored direct logo URLs from external sources. These links often broke due to expiration or CORS issues. We've updated our process to copy and host logo images on our own infrastructure. All newly detected companies will now use a permanent URL format: https://media.theirstack.com/company/logo/xxx.
These links are stable and can be used anywhere.
