Query and document texts are lemmatized, without stopwords
Queries are serialized as trees, for example (JEEP|ДЖИП) (FORUM|ФОРУМ) means (JEEP OR ДЖИП) AND (FORUM OR ФОРУМ).
In other words:
ORs are represented as |-separated lists, i.e. (TERM_A|TERM_B|...)
ANDs are represented as whitespace-separated lists i.e. TERM_A TERM_B ...
