VLOOKUP Not Working Because Of Too Much Text

VLOOKUP will only work to a set limit number of text characters in a cell. So I can search for the value "*orange*" if the cells contain a reasonable amount of text, but as soon as this exceeds some limit, it returns BLANK. I've also tried using INDEX/MATCH with same problem. Is there a workaround or alternative function?

For example:

This will work and return the text in cell A2
A2: The quick brown fox jumps over the lazy dog. Orange. The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog

This will return BLANK
A2: The quick brown fox jumps over the lazy dog. Orange. The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog
