Term_index_interval

Detailed Description An IndexWriter creates and maintains an index.. The third argument to the constructor determines whether a new index is created, or whether an existing index is opened for the addition of new documents.. In either case, documents are added with the addDocument method. When finished adding documents, close should be called. If an index will not have more documents added for Term Index Interval/Frequency. Configuration of term index interval may be required (by default 256) if you have a field or multiple fields that contain very unique values (for example GUID/UUIDs or unique IDs in general). Typically, the lower the TIF the more memory you need, the higher the TIF the less memory you need but the more disk seeks

index.term_index_interval: Set the interval between indexed terms. Large values cause less memory to be used by a reader / searcher, but slow random-access to terms. Small values cause more memory to be used by a reader / searcher, and speed random-access to terms. Defaults to 128. When referring to term numbers, Lucene's current implementation uses a Java int to hold the term index, which means the maximum number of unique terms in any single index segment is ~2.1 billion times the term index interval (default 128) = ~274 billion. This is technically not a limitation of the index file format, just of Lucene's current The termIndexInterval comment and example settings in the example solrconfig.xml file is left over from Solr 3.x versions. It does not apply to the default Solr 4.x installation and its presence in the example is confusing. For maximum efficiency, Hibernate Search batches index operations and executes them at commit time. If you expect to index a lot of data, however, you need to be careful about memory consumption since all documents are kept in a queue until the transaction commit. This class acts as a core component which creates/updates indexes during indexing process. Class declaration. Following is the declaration for org.apache.lucene.index.IndexWriter class −. public class IndexWriter extends Object implements Closeable, TwoPhaseCommit Creates a new config that with defaults that match the specified LuceneVersion as well as the default Analyzer.If matchVersion is >= LUCENE_32, TieredMergePolicy is used for merging; else LogByteSizeMergePolicy.Note that TieredMergePolicy is free to select non-contiguous merges, which means docIDs may not remain monotonic over time. If this is a problem you should switch to Hibernate Search allows you to tune the Lucene indexing performance by specifying a set of parameters which are passed through to underlying Lucene IndexWriter such as mergeFactor, maxMergeDocs and maxBufferedDocs.You can specify these parameters either as default values applying for all indexes, on a per index basis, or even per shard.

An IndexWriter creates and maintains an index.. The create argument to the constructor determines whether a new index is created, or whether an existing index is opened. Note that you can open an index with create=true even while readers are using the index. The old readers will continue to search the "point in time

index.term_index_interval applies when indexing, you can change that dynamically, but it will only apply to new documents indexed. index.term_index_divisor can be changed dynamically and applies immediately. Lower values for index.term_index_interval also control the size of the index on disk.

For maximum efficiency, Hibernate Search batches index operations and executes them at commit time. If you expect to index a lot of data, however, you need to be careful about memory consumption since all documents are kept in a queue until the transaction commit.
