Sybase Search stores its data in a number of proprietary data structures, generically called indexes. See “Indexing document stores” for more information.
Indexing involves three different processes. The first two are fundamental indexer processes and might occur numerous times during one indexing session. The third process occurs as a maintenance operation. These processes are:
Filtering, or parsing, documents and extracting data in memory
Writing processed data to index stripes on disk
Unifying index stripes on disk
