Overview

The filter query allows the user to set a predefined query that will perform each time the VHL search is executed. It is a strategy composed of a term or expression and may have the following fields:

  • ti - title
  • au - author
  • mh - subject descriptor
  • kw - keyword
  • tw - text words (include ti, au, mh, kw)
  • thematic_area - thematic area of the resource
e.g.:  mh:"malaria" AND kw:"vector"

Available fields
