Perhaps you should try some spelling variations:
oxide release » guide release, oxide releasing, amine release
silver oxide » silver iodide, silver bromide, silver halide
vine release » eine release, amine release, time release
silver vine » silver mine, silver nine, silver mines

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( silver oxide release ) OR ( silver vine release ))*.
