Partial search hits on variants

If you search for a title containing almost the entire title of a variant it falls back to the product instead of showing the variant. You need the complete variant number or the complete title to actually get a hit on a variant. We want a config setting that can activate partial hits on variants without a complete match on the title/variant number.

Here is an example of the behavior:

If you search the entire name you get the variant: PROTAN SE1,2 FLAK 4/FL.4 m F91

If you remove one letter it searches only the product: PROTAN SE1,2 FLAK 4/FL.4 m F9
