Examples of org.apache.lucene.index.IndexModifier.deleteDocuments()

org.apache.lucene.index.IndexModifier.deleteDocuments()
Deletes all documents containing term. This is useful if one uses a document field to hold a unique ID string for the document. Then to delete such a document, one merely constructs a term with the appropriate field and the unique ID string as its text and passes it to this method. Returns the number of documents deleted. @return the number of documents deleted @see IndexReader#deleteDocuments(Term) @throws IllegalStateException if the index is closed

            // Delete any conversations found -- they may have already been indexed, but
            // updated since then.
            for (long conversationID : conversationIDs) {
                writer.deleteDocuments(new Term("conversationID", Long.toString(conversationID)));
            }


            // Load meta-data for each conversation.
