Hi Pedro One thing that helps is that Sphinx v2 (which is required for TS v3) now has proper string attributes, so they’re useful for storing values like class names - which is the main thing TS v1/2 used CRC32 for, to figure out what class to instantiate for each record.
String attributes can’t be used for filtering though, so I also add a field with the class name, and add clear conditions for that when searching across multiple classes. Beyond string attributes and filtering on fields instead of attributes… well, it depends what you’re trying to do. Is there something in particular where CRC32 was being used that you’d now like to change? — Pat On 8 Jan 2014, at 4:55 am, Pedro Carriço <[email protected]> wrote: > Hi Pat, > > What other ways have you found to avoid it and what do you recommend for > users migrating from v2 to v3? > > Thanks, > > On Saturday, 14 December 2013 00:14:49 UTC, Pat Allan wrote: > Hi Onno > > That documentation is for v1/v2 of Thinking Sphinx, which added the to_crc32 > method to the String class.
