• As ai usage increases we're getting more query errors, log these so we can get a better idea of what kind of query errors are happening

User-supplied search query values logged via logger.info

The InvalidSearchQuery error message—built from str(error)—frequently embeds the raw user-typed query value (e.g. user.email:alice@corp.com → "user.email: Invalid date: alice@corp.com. ..."). Logging this with logger.info(message) sends that value to a durable application-log sink. Replace with a fixed categorical string or log only type(error).__name__ and omit the user-supplied value.

Evidence

• message = str(error) (line 371) captures the full InvalidSearchQuery string verbatim.
• In event_search.py (_handle_basic_filter), errors are raised as f"{search_key.name}: Invalid date: {search_value.raw_value}. ..." — raw_value is the literal text from the user's search bar.
• A user searching user.email:victim@company.com with an invalid format would produce an error whose string contains the email address.
• sentry_sdk.set_tag("query.error_reason", message) already existed before this PR; logger.info(message) on line 377 is the only new durable sink introduced by this diff.
• Application logs are typically retained and may be forwarded to third-party log aggregators, making this a broader exposure than the existing Sentry tag.

Fix attempt detected (commit 5d74bfd)

The logger.info call was modified to use a static message with the user-derived value moved to extra, but extra={'query.error_reason': message} still embeds the raw user-supplied query string into the durable log record, so the PII exposure persists.

The original issue appears unresolved. Please review and try again.
