I'm attempting to using Sphinx in my CMS as a sitewide search. Since each model in the CMS has different fulltext fields, I've created an index per model. However, according to Sphinx's forum, searching over multiple indexes with different schema is not supported.
How are you CMS guys using Sphinx for your general site search? Performing a call to Sphinx per model and keeping track of pagination offsets? Creating one huge index with an index field per model/field? Is there some other solution I'm not thinking of?
