Improving Heartbeat's Search and Discussion Organization

Our community is large and very active. While resource sharing is abundant and enriching, it becomes difficult to locate these pieces of information after some time in the mix! Here are a few suggestions to improve the experience:

1) A more intuitive and efficient search engine (currently, as soon as we use two keywords, it seems to lose track).

2) A post tagging system, allowing users to search by category (like a database).

3) The ability for members to have a personal library of posts, where they can save the ones they are interested in
