Table 2 Complex search operators used to search the published and grey literature

From: Will environmental flows increase the abundance of native riparian vegetation on lowland rivers? A systematic review protocol

Simplified secondary question Boolean search operator
Do flows increase germination rates? TS1 + TS2 + TS3 + Germination
Do flows increase/decrease survival? TS1 + TS2 + TS3 + Mortality
Do flows increase condition? TS1 + TS2 + TS3 + Condition
Does condition affect reproduction? TS1 + TS2 + Condition + Reproduction
  1. Simplified secondary questions combine all flow types and vegetation responses.
