Hi Pedro In these situations, it might be worth shifting the set into its own model, and then you’ll have a foreign key integer that you can filter by. Of course, using CRC32 is certainly still an option, it’s just not loaded into TS code by default, nor into PostgreSQL databases by default (it’s a default function for MySQL though).
Good luck :) Cheers — Pat On 8 Jan 2014, at 10:34 pm, Pedro Carriço <[email protected]> wrote: > Hi Pat, > > > > At the moment I'm filtering a sphinx search using a string attribute (using > to_crc32), but I still don't know if this is the correct pattern if I just > want a subset of a sphinx search. > The string attribute with I'm filtering is usually something like a closed > set of states, conditions and/or types that the objects might have. > > I'll try to investigate and learn a little bit more about sphinx (because at > the moment my sphinx knowledge is still a bit shaky) and perhaps I'll come up > with a different solution to my problem. > > Thank you for your reply and for all the help. > Keep up the good work on Thinking Sphinx! > > Cheers, > > On Tuesday, 7 January 2014 22:02:43 UTC, Pat Allan wrote: > 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.
