Changes

PostHog/posthog#72992 added four property filter operators everywhere property filters exist: starts with, doesn't start with, ends with, and doesn't end with.

The main motivation: most people use contains for flags and filters that match email domains, which is imprecise. For example, email contains @posthog.com also matches bad-person@posthog.computer.com. The correct regex (@posthog\.com$) is easy to get wrong, so most people default to contains.

This PR updates the docs accordingly:

  • Fixes examples teaching the imprecise pattern – canary release tutorial (email contains posthog.com → email ends with @posthog.com), the "What is a feature flag?" blog post, the filter-internal-users tutorial (doesn't contain @posthog.com → doesn't end with), the cohorts free-email-provider example, and four customer_email contains "@domain" conditions in the support workflows docs.
  • Documents the new operators – added to the canonical property filter operators reference table, the trends filters operator table (with UI glyphs ↦ ↛ ⇥ ⇻), the cohorts person-property operator table, and the flag troubleshooting operator list.
  • Adds guidance – a tip in the operators reference and in the flag release conditions docs recommending ends with over contains for email domain targeting.

⚠️ Do not merge until the operators are GA

The operator dropdown is gated behind the starts-with-ends-with-operators feature flag (currently internal-only, pending SDK local evaluation support). Merge once the flag is rolled out to everyone, so the docs don't describe operators customers can't see.

Known follow-up: the filter-internal-users step 2 screenshot still shows the old "doesn't contain" filter and needs retaking once the UI is GA.

Checklist

  • I've read the docs and/or content style guides.
  • Words are spelled using American English
  • Use relative URLs for internal links
  • I've checked the pages added or changed in the Vercel preview build
  • If I moved a page, I added a redirect in vercel.json (no pages moved)

| `ends with` / `does not end with` | Matches when the property value ends (or does not end) with the substring |
| `matches regex` / `does not match regex` | Matches when the property value matches (or does not match) a regular expression |

> **Tip:** To target by email domain, use `ends with` instead of `contains`. For example, `email contains @posthog.com` also matches `bad-person@posthog.computer.com`, while `email ends with @posthog.com` only matches addresses on that exact domain.

Is this how our contains logic works, it matches even if the string is split?

I'm not sure what you mean by the string is split.

If you're matching "contains '@posthog.com'" it means the string contains @posthog.com anywhere in the string.

bad-person@posthog.computer.com contains @posthog.com

bad-person-->@posthog.com<--puter.com

Recommend ends with over contains for email domain targeting
1b2520f 
Document the new starts with / ends with property filter operators and update examples that used contains to match email domains. Contains is imprecise for domains: `email contains @posthog.com` also matches `bad-person@posthog.computer.com`.

Eager-graph budgets are report-only until a baseline is established. Sizes are gzip of public/**/*.js; eager size is webpack module source bytes for the modules actually shipped in the entrypoint's initial chunks (post-tree-shake).
