One Tracker can monitor up to 15 separate queries about a single campaign or topic. A Tracker will find all tweets that match any of your search queries and aggregate their metrics together in your Tracker, so make sure all the queries in a Tracker are related. You will be able to drill down into some details later (usernames, hashtags, URLs, etc...), but summary metrics will be calculated for the entire set of tweets. 

A Tracker query can consist of any keyword, hashtag, phrase, Twitter username, URL or combination of those. Put each query on a separate line in the Tracked Terms field on your Tracker setup page (see below for an example). Some possible queries include: 

• keyword - search for tweets containing any reference to this keyword
• keyword1 keyword2 - search for tweets containing both keyword1 and keyword2 in any order
• “keyword1 keyword2” - search for tweets containing the exact phrase “keyword1 keyword2”
• username - search for all tweets to, about and from a username
• @username - search for tweets that mention, reply to, or RT username (will not include tweets from that username)
• from:username - search for tweets from a username
• #hashtag - search for all tweets containing #hashtag
• url_contains:bit.ly/123456 - search for all tweets containing this URL or portion of URL

You can also include combinations of multiple terms to narrow down your results (such as username keyword1). Also consider including common misspellings and alternate combinations of your search terms in order to fully capture the concept you're measuring. Do not include OR, AND, +, or - in your queries. Queries are matched exactly (e.g., cat will not match cats). If your query has punctuation in it, it will be matched exactly so use quotation marks around your query (e.g., "ow.ly" or "peanut butter & jelly"). Queries are not case sensitive, so uppercase and lowercase letters do not impact your results.

A Tracker can also exclude tweets that contain certain terms. Just add those words to the Excluded Terms field on your Tracker setup page. Here's an example Tracker setup:
