Hi all,
I am planing to migrate from Lucene 3.5 to Lucene 4.0. But my query does not
work in 4.0.
For example, when I run the following code,
public static void main(String[] args) {
new WildcardQuery(new Term("id", "????????????????????1*"));
}
I encounted OutOfMemoryError: (even if raise Heap Size up to 1GB)
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
at
org.apache.lucene.util.automaton.BasicOperations.determinize(BasicOperations.java:656)

at
org.apache.lucene.search.AutomatonQuery.<init>(AutomatonQuery.java:68)
at org.apache.lucene.search.WildcardQuery.<init>(WildcardQuery.java:57)
In 3.5, I didn't see this error.
I also see simirality error in RegexpQuery with the following code.
public static void main(String[] args) {
new RegexpQuery(new Term("id", ".{20}1.*"));
}
If execute this code, OutOfMemoryError occuered:
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

Does anyone have a same problem? Any advice is appreciated.
Thanks,
