search packet

edit

This is a fairly frequent question, and no you can't filter by column content. You can filter by field and as (almost) everything that is added to the info column is also a field somewhere, you just need to identify the appropriate field.

The general approach to this is to select one of the packets, (by manually reviewing the info column), and then in the packet details pane locate the field that contains the required information. Right click the field, select Apply As Filter -> Selected and the appropriate filter expression will be added to the filter bar and the packet list will be filtered according to the expression.

There is a Lua plugin available that will add another column you can search on.
