+
+This module improves product variant searching by matching the variant
+display name (including attribute values) across all product selection
+fields.
+
+It ensures attribute values shown in the variant name (e.g., “Red”,
+“XL”, “128GB”) are consistently searchable, reducing friction when
+selecting the correct variant.
+
+For flexibility in this module’s ``name_search``, it can be used
+together with
+```base_name_search_improved`` <https://github.com/OCA/server-tools/tree/18.0/base_name_search_improved>`__.

+
+Installation
+============
+
+On installation, post_init_hook assigns search_name for up to 20,000
+products (hard cap) to avoid performance issues in huge DBs. Any
+remaining products must be processed by the “Assign product search name”
+cron job. This cron is disabled by default, so an administrator should
+enable it when needed, then disable it again once all products have
+search_name assigned.
+
+Bug Tracker
+===========
+
+Bugs are tracked on `GitHub Issues <https://github.com/OCA/product-variant/issues>`_.
+In case of trouble, please check there if your issue has already been reported.
+If you spotted it first, help us to smash it by providing a detailed and welcomed
+`feedback <https://github.com/OCA/product-variant/issues/new?body=module:%20product_variant_search%0Aversion:%2018.0%0A%0A**Steps%20to%20reproduce**%0A-%20...%0A%0A**Current%20behavior**%0A%0A**Expected%20behavior**>`_.
