But the "crash.java" is a just single document physically.
Do we have any drawback if we treat each line in "crash.java" as a doucment?
Another question:
If we need to present the search result with the hit lines plus n
lines forward and backword, how can I do this if each lines are
seperated in each document?
for example:
1. contents in crash.java are:
public class crash {
public static void main(String[] args) {
}
}
2. query "main"
3. search result= the hit line +1 line and -1 line
1 public class crash {
2 public static void main(String[] args) {
3 }
