Specify keywords to track. Queries are subject to Track Limitations,
 described in Track Limiting and subject to access roles, described in
 the statuses/filter method. Track keywords are case-insensitive logical
 ORs. Terms are exact-matched, and also exact-matched ignoring
 punctuation. Phrases, keywords with spaces, are not supported.
 Keywords containing punctuation will only exact match tokens.
 Query parameters may be passed as the last argument.
