[PyKDE] eric: do regular expressions work?

I have wrestled a  lot with the eric3 search & replace regexps. Today
I was completely stumped by what seems to me to be a very simple task:
to find the text "time" or "localtime".

With the text:
def today(time=localtime):
    ''' datetime for midnight, today '''
    tm_year, tm_mon, tm_mday, tm_hour, tm_min, tm_sec, tm_wday, tm_yday, 
tm_isdst = time()
    return date(tm_year, tm_mon, tm_mday)

Searching for "time", and "localtime", (separately, and not a regular 
expression) finds these.

Searching for "time|localtime" (regular expression) finds nothing.
The eric regular expression syntax is not documented, so I

"(time)|(localtime)" (maybe alternation has higher precedence than 

"\(time\)|\(localtime\)" (maybe meta-parentheses need to be escaped)

"time)\|localtime" (maybe alternation needs to be escaped)

They all  failed to find "time" or "localtime" in the above text.

Is the regexp search broken, or is the syntax even weirder than what I tried?

Could you provide a summary of the regexp syntax (including valid references 
for replacement text) used in eric?

Could you make the syntax more "normal", i.e. don't escape
parentheses for grouping, or more like (er exactly like!) the KDE text
editor component?
