MyLastSearch can be used to locate your Internet search query history. It scans the cache and history files within your browser, even scanning popular social network sites like Facebook and Twitter, and then displays any search queries you've made in a table.
MyLastSearch will tell you what your query was, which search engine you used, the time you searched, which Web browser was used and the search URL.
Once you have your results, you can then select one or more query and either copy them to the clipboard or save them in a text, html or xml file.
