Find lexemes or lexeme structures in a DeriNet-style database.
You can search for a single lexeme using an attribute expression. Multi-lexeme structures can be found by chaining and nesting attribute expressions.
An attribute expression describes a single node in a derivational tree. It has the following form: [attribute1="regex1" attribute2="regex2" …], which matches a node, whose attributes match the corresponding regexes. Available attributes are lemma, techlemma, pos (part-of-speech), id a parent. id and parent expect a node ID from database as an argument; [parent=="143581" pos=="N"] is equivalent (almost – they differ in highlighting) to [id=="143581"] [pos=="N"]. A special case is [parent=="-1"] – this matches nodes without a parent.
Example: [lemma="vana" pos="N"] matches all nouns, which contain “vana” as a substring.
Apart from = there are other comparison operators: == for string comparison (strings are equal, when they contain the same characters), != a !== for negation of the previous two.
The form "regex" is available as a shortcut equivalent to [defattr="regex"] and string is equivalent to [defattr=="string"]. You can choose default attribute defattr in a dropdown menu under the search input field.
A tree expression describes a subtree. Every attribute expression is also a tree expression; if you concatenate several attribute expressions: balit "ík$" [pos=="N"], you'll find a tree, whose root is the first expression, its son is the second one, which has the third one as its son…
the second form is
aexpr (texpr1, texpr2, …). This matches a subtree, whose root matches the attribute expression aexpr and every tree expression texprX matches one of its sons.
