Just configure the parameters:
Hashtag: filter the search with a hashtag or phrase.
Maximum number of results
Number of search pages (max 15 pages and 100 results per page): note than more pages searched, can causes the module to operate slower.
Is important to have enabled Joomla cache mode so the module does not slow down the web.
Note: This module does not save the results in the database or any file, shows the results of the search with the Twitter Search API (Get Search).
