- Find a handy url-encoding cheat-sheet, like this one: http://www.blooberry.com/indexdot/html/topics/urlencoding.htm. You will have to replace special characters (@, #, :, etc.) with their url-encoded version.
- + and %20 (a url-encoded space) seem to be interchangeable when constructing complex search queries. If one doesn't work in between each search parameter, try the other. (Replace the "+" with OR for searches that return any of the keywords/search parameters, as opposed to all the keywords/search parameters.)
- To see how Twitter itself is constructing a query, do the search in their advanced search (https://twitter.com/#!/search-advanced), then follow this formula to construct your feed:
Take the url that is produced from your search and replace the first part (https://twitter.com/#!/search/) with the rss version (http://search.twitter.com/search.atom?q=).
You will go from this: https://twitter.com/#!/search/librarian%20tattoo
to this:
http://search.twitter.com/search.atom?q= librarian%20tattoo - You can probably replace the ".atom" with ".rss" if you prefer. (As pointed out by @calimae.)
************************
Here are some pre-constructed feeds, where you just replace the bold info with the info you want to use:
Hashtag search: http://search.twitter.com/search.atom?q=%23library
User mention search: http://search.twitter.com/search.atom?q=%40val_forrestal
Specific user's entire timeline: http://search.twitter.com/search.atom?q=from%3Aval_forrestal
Keyword search: http://search.twitter.com/search.atom?q=research+paper
Location + keyword search: http://search.twitter.com/search.atom?geocode=40.744544%2C-74.027593%2C5.0mi&q=+research+paper+near%3A%22hoboken%2C+nj%22+within%3A5mi
User mention + hashtag: http://search.twitter.com/search.atom?q=%40val_forrestal+%23library
User + hashtag: http://search.twitter.com/search.atom?q=from%3Aval_forrestal+%23library
