Twitter Advanced Search is an invaluable tool for searching through Twitter pages.
The most important use is viewing older Tweets. According to Twitter's help center, a user's profile only displays their 3,200 most recent Tweets. Advanced search is necessary to access older Tweets if no image source is available to reverse search.
The second use is to aid in sourcing and BVAS efforts. Many posts are not sufficiently sourced to locate the Twitter post they originated from. If reverse search fails, and the artist's Twitter profile is cut short, the user must input a From this date value preceding the cutoff. A good starting point is the day before the Joined <month> information at the top of a user's page.
For example, the profile of artist NyaswitchNya is cut off on Jun 19, 2019 for me as of typing this, whereas advanced image search yields results from mid-October 2017 and image posts starting in January 2018. These posts were not found through any reverse search engine, and uploads that pulled from them would have otherwise remained unsourced or unflagged if BVAS.
For the above reasons, I strongly suggest mentioning Twitter Advanced Search in the detailed section for Twitter, either as part of the main body or a collapsible section with additional information.
