Ask HN: Why are tech job sites so ineffective?

I've been in tech for over 20 years and I'm also frustrated how difficult it is to use job sites including LinkedIn and Indeed which seem to be the major players now.

For example, if I wanted to find a job that involves using Rust on a daily basis it involves a lot of manual filtering. This is because languages tend to be lumped together in phrasing like "one or more of the following languages are ideal" but then they don't qualify the ones they actual use.

New job sites seem to pop up all the time but are pretty similar and may only be marginally better because they're more specialized.

Am I missing a better way to find the job I really want without having to read through hundreds of job descriptions? Does the industry need a "spec" for posting jobs?
