Perhaps you should try some spelling variations:
candidates processing » candidate expressing (Expand search), candidate proteins (Expand search)
decrease candidates » decrease candida (Expand search), diseases candidates (Expand search), license candidates (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), not decrease (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease AND decrease candidates processing ) OR ( decrease toc decrease toc decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease AND decrease candidates processing ) OR ( decrease toc decrease toc decrease ))*.
