  • Toggle checkbox to restrict the search to the current module( such as RIFLEX,SIMO,etc.).
  • You can control the search by using the following operators:
  • Wildcards:
    • *node (Words ending with node)
    • node* (Words starting with node)
    • *node* (Words containing node)
  • Title heading:
    • title:node (Word node in title)
  • Keyword ranking:
    • sand^10 material (sand is 10 times more important than material)
  • Keyword exclusion and inclusion:
    • node +fixed -parameters (must contain fixed, might contain node and must not contain parameters)
