issue2551189 - increase text search maxlength This removes I think all the magic references to 25 and 30 (varchar size) and replaces them with references to maxlength or maxlength+5. I am not sure why the db column is 5 characters larger than the size of what should be the max size of a word, but I'll keep the buffer of 5 as making it 1/5 the size of maxlength makes less sense. Also added tests for fts search in templating which were missing. Added postgres, mysql and sqlite native indexing backends in which to test fts. Added fts test to native-fts as well to make sure it's working. I want to commit this now for CI. Todo: add test cases for the use of FTS in the csv output in actions.py. There is no test coverage of the match case there. change maxlength to a higher value (50) as requested in the ticket. Modify existing extremewords test cases to allow words > 25 and < 51 write code to migrate column sizes for mysql and postgresql to match maxlength I will roll this into the version 7 schema update that supports use of database fts support.
