Perhaps you should try some spelling variations:
information documents » information documentation, information agents, information requirements
first precision » first revision, finite precision, dies precision
first decision » first division, first revision, first session
elastic liner » elastic linear, elastic line, elastic layer
plastic liner » elastic linear, plastic pipe

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

• Performing a fuzzy search may retrieve terms with similar spellings: information documents ((first precision) or (first decision)) ((elastic liner) OR (plastic liner))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information documents ((first precision) OR (first decision)) ((elastic liner) OR (plastic liner)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "information documents ((first precision) or (first decision)) ((elastic liner) OR (plastic liner))".
• Adding a wildcard symbol may retrieve word variants: information documents ((first precision) or (first decision)) ((elastic liner) OR (plastic liner))*.
