Context

2014-05-26
16:40		Fix a problem in FTS4 where columns with names that are prefixes of any notindexed column were also being (incorrectly) marked as not indexed. For example in "CREATE ... t1(abc, bc, abcd, notindexed=abcd)", both abc and abcd were being treated as notindexed. (check-in: d90c4964 user: dan tags: trunk)
