"options format :",
" option*",

" Available option :",
" - 'full_context' : extract all the log that are in the context of a ",
" selected log",
" - 'output_prefix='<prefix> : set a prefix for the result file of the query",
"",
"logicalCombiner format :",
" Supported logical combiner are 'or' and 'and'.",
" The 'and' combiner have the hightest priority over 'or'.",
" You can also manually force the priority of combiner by",
" grouping predicate with parenthesis.",
" e.g : '(' predicate1 'or' predicate2 ')' 'and' predicate3'",
" In this case, the 'or' between predicate1 and predicate2 is avaluated ",
