text: maximum disk space required = Number of documents x document size x 150% 
  
  The actual percentage, 50% through 150%, is data-dependent. So, an exact number can be 
  obtained only by testing with your data. 
  
  For example, 100,000 documents of 20 KB each can require about 1500 MB (100,000 x 
  20 KB x 75%) of disk space. 
  
  **Tip:**To determine the text size for AFP and Line Data documents, extract a sample 
  document and use the**arsview**server command to determine the text size. 
  
  The size of the index is not limited. However, when data is added to or removed from a text 
  index, the text index structure is merged to improve query performance. The required 
  processing time to complete the merger depends on several factors, such as index size and 
  absolute throughput (which in turn depends on the data type and index format). These factors 
  result in practical limits on the total text index size. 
  
  For query performance, the biggest impact is the number of matching results, not the size of 
  the text index. 
  
  **Temporary disk storage**
  During the indexing process, the server requires additional disk space for temporary storage. 
  The maximum required disk space is approximately four times the total size of the text of the 
  documents that are indexed.
