How to improve Sphinx relevancy?

Question

Sphinx

Can't beat and improve Sphinx relevancy
Have search query "T4P (25030124) SKELETAL LEVEL 1200mm"
Have sphinx result:
T4P level 2503905 (Item code: 86200; Weight: 491689)
T4P level 2503004 (Item code: 88811; Weight: 491689)
T4P level 2503008 (Product code: 88812; Weight: 491689)
T4P level 2503112 (Product code: 88813; Weight: 491689)
T4P level 2503920 (Product code: 98089; Weight: 491689)
T4P level 2503018 (Product code: 98093; Weight: 491689)
T4P Level 2503206 (Item Code: 98094; Weight: 491689)
T4P Level 2503210 (Item Code: 98095; Weight: 491689)
T4P Level 2503215 (Item Code: 98096; Weight: 491689)
T4P Level 2503910 (Item Code: 98; 09: 98; Weight: 491689)
T4P level 2503010 (Product code: 98100; Weight: 491689)
T4P level 2503012 (Product code: 98101; Weight: 491689)
T4P level 2503015 (Product code: 98102; Weight: 491689) T4P
sanding paper Weight 2204320 (Product code: 86220) : 487190)
Hacksaw T4P 2601052 (Item code: 86207; Weight: 487190)
T4P pliers 3501123 (Item code: 86208; Weight: 487190)
A number of results are obtained with one weight. But one result should obviously be more relevant, I highlighted it in bold, since I simply added 4 to the product code "T4P Level 2503012" in the query, if you search correctly, then this product has the largest weight, if you add a number at the end of the code, then a lot goods becomes with one weight.
Here is my config:

index test045{
  source          = test045
  path            = /var/lib/sphinxsearch/data/test045
  docinfo         = extern
  morphology      = stem_enru
  html_strip      = 1
  min_infix_len   = 1
  enable_star     = 1  
  index_exact_words = 1
  expand_keywords = 1
  charset_type    = utf-8
}

Please help me fix the config so that when searching for Level T4P 2503012 and Level T4P 2503012 4 , the item Level T4P 2503012 is displayed as the most relevant. Thank you.
