Introduce Search syntax for board

Currently it is difficult to use search on larger boards due to a big amount of false positives. For example if I try to find ‘customer experience’ I am getting all items with customer or experience it in, not even sorted by proximity.
Same goes for ‘SLA’ - everything which contains these threee characters at once is returned.
Please provide functionality for phrase search (like quotes, ‘Customer Experience’ and mandatory keyword search (+experience)
Thank you!

Phrase search works for me.

If I search “timber” I get lots of items. If I search “timber panelling” it returns only one item - as expected.
