Perhaps you should try some spelling variations:
communication connection » communications connections, communication connecting, communication collections
chart parsing » chart pursuing, fast parsing, hand parsing
basic parsing » basics passing, basic nursing, based parsing
basics linear » basic linear, based linear, basics clear
arc parsing » lr parsing, arc paving, data parsing

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

• Performing a fuzzy search may retrieve terms with similar spellings: communication connection ((((arc parsing) OR (chart parsing))) or (basic parsing)) basics linear~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication connection ((((arc parsing) OR (chart parsing))) OR (basic parsing)) basics linear*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "communication connection ((((arc parsing) OR (chart parsing))) or (basic parsing)) basics linear*".
