It would be great to be able to search using multiple terms. I suspect that a lot of people, like me, use tags in a way similar to folders or categories. It would be very helpful to search for multiple terms, especially using AND/OR/NOT/NEAR as qualifiers. Workflowy and Dynalist allow for search with multiple terms (which can be saved in Dynalist), and Roam in effect does this through its use of filters in searches. Thanks.
