Deleting documents using "starts with"
I currently have code that looks like:
Term[] terms = new Term[]{
new Term( key1, value1 ),
new Term( key2, value2 )
};
writer.deleteDocuments( terms );
I want to change things such that it will delete all documents having
key2's value start with value2, i.e., if value2 were "foo" then I want
all documents to be deleted where key2's value starts with
"foo" (i.e., "foo*").
I still want key1's value to match value1 exactly, however.
What's the simplest way to do do what I want? Thanks.
- Paul

There are IndexWriter.deleteDocuments methods that take queries.
Passing a TermQuery and a WildcardQuery to
writer.deleteDocuments(Query[]) should do the trick.
