It would be nice to have a filter in the char bazaar, an inline list that can work as tags (separated by comma) to filter by skills. Like: Amarr Carrier 5, Tactical Logistics Reconfiguration 5, Fighters 4, Capital Remote Armor Repair Systems 5… etc
This should probably be the minimum so if I search for Minmatar Dreadnought 4, those with level 5 could be included too.
Very possible with the appropriate restrictions, searching through the initial char that posted as well the non-locked threads.
Other options could be standings. I’m going nuts searching for a toon with good standings for a certain faction and that is not sold already.
