OR Selects documents that show evidence of at least one of the search elements you specify. Documents are ranked based on the number of search elements found. Modifiers Modifiers are used with operators to further refine search parameters. You can specify case sensitivity in a query, or force the output to be ranked by relevancy. For example, you can use the CASE modifier with an operator to specify that you want to match the case of the search word.
Searches are case-insensitive for search text entered in all uppercase or all lowercase.
Case sensitivity is activated when mixed case characters are entered. MANY - Results are ranked by relevancy, determined by the number of times the search value is found in a document. Used only with the AND and OR operators.
