Why? object_implements indexes a list of interface dotted names. Would another type of index be more appropriate? >> UID |FieldIndex |0.0003070| 3257.1 > > Note that this is the worst-case scenario for a FieldIndex: there is > exactly one value for every key. This shouldn't be "indexed" at all, in > fact, beyond a simple BTree (UID -> rid). Good point. I wonder how many places we use a UID index. UID *metadata* is quite important, of course. >> targetUID |FieldIndex |0.0002287| 4372.12 > > I don't know what this one is used for, but it should probably be > scrapped as well. Me neither ... sounds bogus. >> Title |ZCTextIndex |0.0000128| 77809.46 > > This should be removed: there is no valid use case for doing a > full-text search restricted only to the title. I'm pretty amazed that this is a ZCTextIndex as well. I always thought it was a FieldIndex. >> Description |ZCTextIndex |0.0000116| 86241.39 > > Again, should be removed. Right. >> getEmail |ZCTextIndex |0.0000113| 87849.05 > > Should *definitely* be removed: how can you do full-text search on an > e-mail address? Surely this is application specific too? I don't think Plone has such an index. >> SearchableText |TextIndex |0.0000113| 88466.69 > > Where did this one come from? The 'SearchableText' above is a ZCTextIndex. It certainly is in vanilla Plone. Martin -- Author of `Professional Plone Development`, a book for developers who want to work with Plone.
