Best advice here is to look hard at admin/analysis and see. But a couple of notes: 1> it's usually unnecessary to include the exact same synonyms in both query and index time chains. Index-time is preferred.
2> putting lowercasefilter in front of worddelimiterfilter is going to break wdff _if_ you intend camel-case to produce multiple tokens. 3> brackets? did you mean parentheses? If so I suspect your issue is in your request handler not your analysis chain. Perhaps something with autogeneratephrase? Providing the &debugQuery=true output would help.
