It sounds like your problem is that your id field is analyzed and as a result contains more then one token per document ... both the deleteDocument and updateDocument methods that take in a Term only remove documents that have that exact Term in them.
You need to add your documents with the "id" field as UN_TOKENIZED in the first place, and then updateDocument and deleteDocument should work (note: your use of "\"" in building your Term also looks suspicious, like you expect ther Term text to be analyzed into a phrase .... it's not, it's literal term text). : id:"com.mycompany.myapp.FooBar 142" : Term term = new Term("id", "\"" + doc.get("id") + "\""); -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
