app/vmui: add search for filtering fields in expanded log entries

[Loori-R]

Describe Your Changes

Add a search field for filtering log fields by name and value in expanded log entries in the Group tab. This makes it easier to inspect logs with many fields without using browser page search.

Changes

• add search for filtering fields by name and value in expanded log entries in the Group tab
• show search field only when a log contains more than 8 fields

LGTM, with a few nit comments

[arturminchukov]

LGTM! Just want to suggest an enhancement. Does it make sense to add a top-level search by fields? For example, you enter the fields you are looking for in the top of groups, and when you expand the log, you see the already filtered fields. This will be a little more convenient than re-entering the field name each time you expand the log.

I originally designed this feature more as a field inspector for a single expanded log entry.

Users already have ways to surface important fields directly in the log row (for example via show as message), so I’m not sure global field search is the best default UX here.

Possible alternatives:

1. A single top-level search.

   • Might be confusing, since users could expect it to search log rows/messages rather than fields inside expanded entries.

2. A shared state between multiple inner search inputs.

   • Solves the re-entering problem for multiple expanded entries.
   • However, the input still looks local while affecting other expanded entries as well.
