Shopify Search & Discovery

So it took me a while to find an app that would do exactly what I needed and this does it. Complimentary products because I have several items all with the same design and each has a unique design number in the title like BL#7. Only reason I did not give a 5 was because the search function when searching for items to add to the complimentary doesnt work well at all. Search for BL#7 and you get 50 items with BL#105 etc. If the search function returned only the matches it would be perfect.
