1. Use the asterisk (*) sign: To broaden your search, use an asterisk (*) at the end of a word or partial word. For example, "auto*" would return all postings starting with "auto", such as "auto" or "automobile" or "automation", etc.
2. Use quotation marks (" "): For exact results, use quotation marks (e.g., "ac adapter"). If the results are not satisfactory, try again without quotation marks (e.g., ac adapter).
3. Use the plus (+) sign: When using the operator "+" a keyword will definitely appear in the search results (i.e. "red+apple" will return results containing "apple", but may not contain "red", although those with the word "red" will be listed first.) Please note: Do not leave any spaces between the "+" sign and the keyword.
4. Use the minus (-) sign: When using the operator "-" sign, a keyword will not appear in the search results. (i.e. "apple-red" will return all results containing "apple", but no results containing "red" will appear.) Please note: Do not leave any spaces between the "-" sign and the keyword.
5. Remember, make sure that no punctuation marks except +, -, and " " are included in your keyword phrase (i.e. bearing 3000/sec).
