Hi,
In a program I have indexed 10 files. When I do a search using the query
"contents:java", it will return 2 documents. But when I give
"-contents:java", then it will return an empty result set. Does anyone
know what the right query string for this? I.e., to retrieve all
documents that does not contain the word 'java'.
Please see FAQ of Lucene:
How does one determine which documents do not have a certain term?

Thank you,
Koji
