Advanced Level Sequencer filter

Hello I need regular expressions such as AND, OR, NOT to the search filter of level sequencer. When you have a complex sequencer that manipulates many actors, I think the level sequencer needs advanced capabilities to filter out specific actors. What do you think this idea?

For example,if you enter"Camera|Actor",only tracks that have either “Camera” or “Actor” in their names will be displayed.
You can use it with content browser filters.
