After our initial call, where we created mockups for all the features the new search form should offer, we had a follow-up meeting to review them and confirm that nothing was missed and that both teams fully understood the mockups and their assumptions. Lina Wolf, Marcin Sągol, and Tymoteusz Motylewski participated in this session. Following this meeting, Marcin created a technical document (TYPO3 Documentation Search Improvements Initiative) detailing the current implementation of the search and indexer apps, along with all the planned changes, describing each new mockup and its intended behavior.
