Smarter Search functions in AJO/AEP for audience and journeys

Description -

When searching for audience and journeys, I want to be able to search by including AND excluding terms.  I want smart search.   

Why is this feature important to you -

We mark several of our journeys as DEMO and Test, for earlier versions.  I should be able to search for a specific name and exclude a letter combination that I do not want. 

Also I want to be able to say it Contains  "XYZ" & "ABC", instead of needing to know the exact spelling of the journey every time. 

As we empower more teams to work on the tool, and create more journeys it become more challenging to reference journeys created weeks/months 

How would you like the feature to work -

I want a smart search feature OR the ability to filter results in the left panel by including/excluding specific terms.

I would like a close match capability as well.  

Current Behaviour -

Only can search for specific phrases.  If there is an extra space or typo in the search it will return no results.  Currently I need to know the exact spelling of the journey every time or receive no results.
