Be like Google! Build a graph! I use a free, open-source knowledge graph database[1] with an Emacs frontend. It resembles tree-based knowledge schemes like FreePlane or Org Mode, but things can have multiple parents, not just multiple children. It offers full-text search via Apache Lucene, which resembles regular expressions but also offers boolean operators. It also lets you selectively merge your knowledge base with other peoples' -- share what you want with who you want, without having to segment your experience of the data into separate files.
