Abstract
A computer-implemented method for checking a search query used for retrieving information from a collection of records in an event sequence analysis system is disclosed. The method includes receiving a search query including a plurality of predicates and one or more constraints each associated with plural predicates, in which each predicate is specified to be positive or negative, and the plurality of the predicates forms a logical graph together with the one or more constraints. The method also includes generating from the graph a subgraph including one or more predicates specified to be positive among the plurality of the predicates. The method further includes determining whether the subgraph has plural components or not, and invalidating the search query in response to the subgraph being determined to have plural components.
