One place where a word of the dictionary (note: Dictionary) appears in a file: the file, the line, the position (23 passages, no note), the words as written, the enclosing section (note: Section) and eighty (3 passages, no note) characters (16 passages, no note) of context (note: Passage). Occurrences are what the tool records first; everything else, links, keyword pages, the to-do page (note: To-do page), derives from them. Code blocks, URLs, frontmatter (note: Frontmatter) and link targets (15 passages, no note) never yield occurrences. An expression (57 passages, no note) contained in a longer recognised expression (3 passages, no note) is not counted twice ("keyword page" counts once, not also as "page"); two expressions that only partly overlap, such as "build log (note: Build log)" and "log summary (24 passages, no note)" in "the build log summary", are each counted.
Not to be confused with
A mention, which is an occurrence or a written link (note: Link) seen from the entity (note: Entity) it cites (31 passages, no note), as the entity page (note: Entity page) lists it.
