Overloaded. Adds a document to this index, using the provided analyzer instead of the one specific in the constructor. If the document contains more than {@link #SetMaxFieldLength(int)} terms for a given field, the remainder are discarded.
. 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.
Returns the number of documents currently in this index. If the writer is currently open, this returns IndexWriter.DocCount(), else IndexReader.NumDocs(). But, note that IndexWriter.DocCount() does not take deltions into account, unlike IndexReader.NumDocs().
The maximum number of terms that will be indexed for a single field in a document. This limits the amount of memory required for indexing, so that collections with very large files will not crash the indexing process by running out of memory. Note that this effectively truncates large documents, excluding from the index terms that occur further in the document. If you know your source documents are large, be sure to set this value high enough to accomodate the expected size. If you set it to Integer.MAX_VALUE, then the only limit is your memory, but you should anticipate an OutOfMemoryError. By default, no more than 10,000 terms will be indexed for a field.
Setting to turn on usage of a compound file. When on, multiple files for each segment are merged into a single file once the segment creation is finished. This is done regardless of what directory is in use.
