If `_name_search` is called with `limit=None` it could take time in the loop
because `_name_search` for `product.product` has `limit=100`, i.e. it could be
100 iterations to scan 10 K products. To solve this problem, call `_name_search`
with `limit=None` to get all product variants at once.
As an example, the problem is reproduced on using menu `Manufacturing > Products
> Bills of Materials`, which makes following search query:
```
["|", ["code", "ilike", "XXX"], ["product_tmpl_id", "ilike", "XXX"]]
```
for which ORM calls `_name_search`:

In a customer database, this speeds up the query from 70 seconds to 3,5 seconds.
