Cross-check your query with one or more keywords of your choice (manually), you just have to enter your additional keyword in the query area and validate it.
It is possible to use the Boolean logic operators AND, OR and NOT. You need to enter these operators in uppercase and validate it.
We can also refine the query using one tag for the keywords
Query : (Magnetic) (gear) equivalent to (Magnetic) AND (gear)
Query : (Magnetic gear) equivalent to magnetic gear in one term !
