[FIX] website: Handle matching words with point or slash

Fix an issue where products with internal references containing point
or slash were not recognized as direct matches in the website searchbar.
Instead, fuzzy search was used to find similar words.

This commit addresses the problem by fixing the regular expression
used for matching words in Odoo's search functionality.
