Multiple errors when searching records. Blob, inconsistencies, XML and others. Stack Error:

I get the following errors a lot when searching for records in the Oracle SQL database with PL/SQL Developer.
Not sure where to even start with 5 different error codes. Does this mean 5 separate issues to correct before the code can do its job?

I looked up blob field. It sounds like I need to address some issue before searching for a word like ' Clean Up '. I do not know if PL/SQL Developer does not like the space between the words or if the tables themselves have to have a special modification for Blob fields. I know that they are like large Comment fields with large numbers of character spaces. 500-1000+
Any thoughts on the error?
