Wildcards and truncation

Use wildcard and truncation symbols to expand or focus searches. The system retrieves up to 300 matches to search terms when you use wildcards or truncation.

 Note: For non-Latin script search terms, truncation can be used for Bengali, CJK (Chinese, Japanese, and Korean), Devanagari, Tamil, and Thai scripts only. For other supported non-Latin scripts, use browsing for automatic truncation.
