Perhaps you should try some spelling variations:
"air apparent" » "aire apparent", "fair apparent", "air aparente", "air apaparente", "air apparental"
"kerr apparently" » "kerr aparentely", "kerry apparently", "kern apparently", "kerr apaparentely", "kerr apparentally"
"weir apparent" » "weir aparente", "weis apparent", "wei apparent", "weil apparent", "weir apaparente", "weir apparental"
"weir parent" » "weis parent", "wei parent", "weil parent", "weir aparente", "weir parental"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("air apparent") OR ("kerr apparently"))) OR ((("weir apparent") OR ("weir parent"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"air apparent\") OR (\"kerr apparently\"))) OR (((\"weir apparent\") OR (\"weir parent\"))))".
• Removing quotes may allow a broader search: (((( air apparent ) OR ( kerr apparently ))) OR ((( weir apparent ) OR ( weir parent )))).
• Adding a wildcard symbol may retrieve word variants: (((("air apparent") OR ("kerr apparently"))) OR ((("weir apparent") OR ("weir parent"))))*.
