Field MultiSearch with separator

This module changes how Odoo interprets what you type in search fields, across all screens that use a search box.

• A system setting called multi_search_separator is created with the default value |; ,. This defines which characters act as separators between several search values.
• When you type a search term that starts with / and contains one of those separators, Odoo splits the text into the individual values and searches for records matching any of them (an OR search) instead of treating the whole text as one single value.
• The behaviour is applied at the base level of Odoo, so it works on every model and every search view, not only on one screen.
• If no separator is configured, or the search text does not start with /, the search behaves exactly as before.

There are no new menus, buttons or reports. The change is invisible except in the search results: one search can now cover several values at once. The setting can be adjusted by administrators through the technical configuration parameters.
