The method to use to handle numbers when indexing. Use one of the following options:

0 Do not index numbers.
1 Index all numbers (irrespective of whether they appear on their own or as part of a word).
2 Index numbers only if they are part of a word (for example, DRE4, Y2K, and so on).

If you change this setting after you have indexed content into IDOL Server, the new setting applies only to new content, and the server logs a warning. To clear the warning and ensure that your change applies to all your content, you must initialize your index and reindex the content.
