com.browseengine.bobo.api.BoboIndexReader.deleteDocuments()
com.esri.gpt.catalog.context.CatalogIndexAdapter.deleteDocuments()
Deletes a collection of documents from the index. @param uuids the collection of document UUIDS to delete @throws CatalogIndexException if an exception occurs
de.bwaldvogel.mongo.backend.MongoCollection.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
org.apache.lucene.index.IndexReader.deleteDocuments()
Deletes all documents that have a given term indexed. 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. See {@link #deleteDocument(int)} for information about when this deletion will become effective. @return the number of documents deleted @throws StaleReaderException if the index has changedsince this reader was opened @throws CorruptIndexException if the index is corrupt @throws LockObtainFailedException if another writerhas this index open (write.lock could not be obtained) @throws IOException if there is a low-level IO error
org.apache.lucene.index.IndexWriter.deleteDocuments()
Deletes the document(s) containing term.
NOTE: if this method hits an OutOfMemoryError you should immediately close the writer. See above for details.
@param term the term to identify the documents to be deleted @throws CorruptIndexException if the index is corrupt @throws IOException if there is a low-level IO error
org.apache.lucene.index.RandomIndexWriter.deleteDocuments()
org.apache.lucene.index.TrackingIndexWriter.deleteDocuments()
Calls {@link IndexWriter#deleteDocuments(Term)} andreturns the generation that reflects this change.
org.apache.lucene.search.NRTManager.TrackingIndexWriter.deleteDocuments()
org.springmodules.lucene.index.core.DefaultLuceneIndexTemplate.deleteDocuments()
org.springmodules.lucene.index.factory.LuceneIndexReader.deleteDocuments()
@see org.apache.lucene.index.IndexReader#deleteDocuments(Term) @throws IOException
