If you want to narrow down where in the metadata documents Beija-flor searches in, use Fielded Searches. Pick a topic to search on from the ‘Search Topic’ picklist. Once picked,the 'textbox' beside the picklist becomes active, populated with invisible values for the field being searched. Once you start typing in the 'textbox' the values would auto-complete. For example, if one picks 'Project’ from the picklist, then a list of possible projects (e.g., Boreas, Climate collections) are available for selection in an autocompletion type. Click on one to move it to select.
