In this interface, a search string consists of a sequence of node- or word line searches, separated by underscore (_). Both function and form can be searched for, separated by ':'. Consider the following examples:
When enclosed in brackets, node- or word searches can be marked as optional ('?' - 0 or 1), multiple ('+', 1 or more) or optional/multiple ('*', 0 or more):
Word forms or regular expressions matching word forms, are enclosed in double quotes. If combined with function- and/or form conditions on a given line, the word form comes after the category-specifications, and is separated from the latter by a space:
Nodes are marked by a tilde (~) after the search pattern. Note that if you don't mark a node as a node, the search will only go on to look for immediately adjacent lines, not adjacent nodes.
