This fact alone explains why tools for searching Twitter like this one are so widespread.
Moreover, a search tool such as this one can be used to measure trends as they come and go. That is definitely useful for those who have a brand to look after and need to measure the efficacy of any campaign they are currently carrying out, or that they intend to carry at a later date.
The search itself takes into consideration several modifiers, including exact phrasing, the use of hashtags, and the ability to find tweets whose content can be mainly negative or positive.
As regards the presentation of queries, they are found at the bottom of the screen, grouped together so that you can backtrace your steps and also keep track of every conversation in an ordered fashion.
