The search engine can be configured by the e interface:
Configuration:
e cmd.hit = x ; command to execute on every search hit
e search.distance = 0 ; search string distance
e search.in = [foo] ; boundaries to raw, block, file, section)
e search.align = 4 ; only catch aligned search hits
e search.from = 0 ; start address
e search.to = 0 ; end address
e search.asmstr = 0 ; search string instead of assembly
e search.flags = true ; if enabled store flags on keyword hits
search.align variable is used to determine that the only valid search hits must have to fit in this alignement. For example. you can use e search.align=4 to get only the hits found in 4-byte aligned addresses.
The search.flag boolean variable makes the engine setup flags when finding hits. If the search is stopped by the user with a ^C then a search_stop flag will be added.
