How many lucene indexes do you have? Lucene has no concept of main or
child indexes. To remove all docs from an index for a given indexed
field write.deleteDocuments() is the way to do it, although in your
case probably by Term, like your code sample: Term term1=new
Term("name","D111-123-987.txt") assuming that is the correct indexed
value. Using a WildcardQuery doesn't make sense here.
Repeat for any/all indexes.
