If you want to search this withH or Ha Har Harr then this facility provided

Else if you really want to search it with arry or rry basically any word
in it, then you may saev every book name as SetString

Hi ,
I have a chained task which runs every 1 second(Still wondering how can i
run it every 3 seconds)
Task code is something like this
try{
//Do something
//read data store and update datastore
}catch(Throwable ex){
I have not mentioned any retry count...so i guess whatever the default one
is being used. (Actually i never want to retry if one fails next one will
take care .. Do you know how to never retry a task.)
