It seems like the ordering of lexemes in tsvector has changed from 8.3 to 8.4.
For example in 8.3.1, postgres=# select to_tsvector('english', 'quit everytime'); to_tsvector ----------------------- 'quit':1 'everytim':2 The lexemes are arranged by length and then by string comparison. In postgres 8.4.1, select to_tsvector('english', 'quit everytime'); to_tsvector ----------------------- 'everytim':2 'quit':1 they are arranged by strncmp and then by length. I looked in tsvector_op.c, in the function tsCompareString, first memcmp and then length comparison is done. Was this change in ordering deliberate? Wouldn't length comparison be cheaper than memcmp? -Sushant. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
