Translations:Setting conditions/3/en
From LimeSurvey Manual
Starting in Version 1.92, all navigation and branching is controlled by Expression Manager (EM). You can still use the Conditions Editor as described below. However, internally, Expression Manager converts the Conditions to a relevance equation. LimeSurvey only reads the relevance equations during survey-taking, thereby eliminating the need for multiple database reads against the conditions table.
