[Fofredux-devel] Search and tags

[Andrew T. <ajt...@hi...>]

For storing searches, do we just have a table of SQL "WHERE" clauses,
or do we attempt to store more complex columns? I will want to do
searches/aggregations like:

terms:
feeds:
tags: unread, mac, programming
when: 04/01/04 to 05/320/05

terms: illinois governor OR congress
feeds:
tags: read
when:

Are these columns enough?

What are "Tags in tags"? Do you want to create a tree (politics ->
republican, wig, independent; computers -> mac -> programs, windows),
or just sets (computers -> mac, windows; technology -> mac ->
programs, palm -> programs, gadgets)

Trees/sets could get fairly ugly trying to maintain, don't you think?
Categories could just be "collections" of tags? Again, seems like a
complicated matter.
