They would be filed in California state court, not federal, so they wouldn't be in PACER. California state courts are a PITA to search, because you have to do it county-by-county, and some counties charge to use their websites. (I'm not even sure if all California counties are online.) Eventually, cases will show up on Lexis or Westlaw, which xraider has access to, but that can take saveral months.
The last time xraider checked the more populous counties (during PD'08, I think), nothing showed up.
