- Search for a particular user's post: user:somebody
- Search for the same user, but only times they said "cheese": user:somebody,cheese
- Search for the same user, but only in the item "idkfa": user:somebody,item:idkfa
- Search for anywhere people mention "cheese": cheese
- Find all mention of cheese in "idkfa" for a set of users: item:idkfa,user:somebody,user:nobody,cheese
- Only the "roots" of threads, not the replies: is:root
- Find comments mentioning both cheese and crackers in the last five days: last:5d,cheese,crackers
- Find comments mentioning either cheese or crackers: cheese+crackers
- The item, user, and last prefixes can be negated, for example, posts older than 5 days, not in "idkfa": -last:5d,-item:idkfa
- All posts in direct reply to your comments, excluding when you replied to yourself: inreplyto:me,-user:me
- All posts in reply to threads that you've started (but not necessarily in reply to you): threadreplyto:me,-user:me
