Extended search, unlike the common one, only works with exact expressions.

Searched expression must be exact, but it does not need to be complete. E.g. start or end of the expression should be enough. Uppercase, lowercase and diacritics do not matter.

Extended search is great for looking up products where e.g. product code starts and/or ends with the same expression. You can also use extended search to seach in product description.

In case of multiple-word search, separate each word with space (e.g. if you are looking for a product with 3-word name, you can enter just first and last word; you just need to keep the correct order of words).

If you do not need to search strictly in product code, PN, name or description, use the common search, which is also able to work with singular/plural forms, shortcut words etc.
