Build the construction by dragging groups, words and roles from the box onto the field. Node 1, at the top, is what each result is; the nodes below a node are inside it, in the order of the text (right to left in Hebrew, left to right in Greek). Drop a new node on the middle of a card to put it inside, on the card's edges to put it before or after it, or on the strip above the tree to put the whole pattern inside it. Cards can be dragged to another place, or back onto the box to remove them (or click a card's ×, or select it and press Delete). Clicking an item in the box adds it inside the selected card.
Click a card to change it below the field. A node inside another is found directly in it (a child in MACULA's tree) or anywhere in it (at any depth); is or is in also accepts the node itself, which matters for roles: a one-word subject is the word itself, a longer one is a group around the words. Mark a node not to exclude results that contain it, and tick in this order to require the nodes inside to follow each other in the text.
Groups have a class (clause, noun phrase, prepositional phrase, relative clause…) and a rule; words have a class (noun, verb, preposition…), lemma, type, stem… Both can have a role in their clause (subject, object, verb, predicate, adverbial…). Each node offers only the attributes and values that occur on its kind of node in MACULA; a typed value that never occurs there is marked red. Lemmas and words are compared without points or accents. In Greek, words also have case, tense, voice and mood, and clauses can have an indirect object, a copula (εἰμί, γίνομαι) or an address or interjection (κύριε, ἰδού: MACULA's role “aux”).
