How to configure sphinx to search for products by price list?

Question

Sphinx

I'm trying to collect prices for items. I take a lot of yml and drive it into the database. Product names are like this

Планшет ASUS Transformer Pad TF 303 CL 16 Gb LTE Dock синий (90 NK 0141-M 00920)               |
| Мобильный телефон Samsung GALAXY S5 mini SM-G 800 F синий                                      |
| Мобильный телефон Samsung GALAXY S5 mini SM-G 800 F черный                                     |

| Планшет Wexler ULTIMA 7 3G 8Gb черный                                                          |
| Планшет Wexler ULTIMA 7 3G 16 Gb черный                                                        |
| Планшет Wexler TAB A 740+3G 4Gb черный                                                         |
| Планшет Wexler TAB A 742+3G 4Gb черный

My products are named simply

Samsung GALAXY S5 mini
Wexler TAB A 742
ASUS Transformer Pad TF 303 CL

With goods like Samsung, it turns out that often the model code is indicated in yml. For example Samsung galaxy gt9092 s4. Tell me, how best to configure sphinx to search through such strings in order to select the maximum number of matches, but at the same time not make an erroneous choice?

Answer 1

min_word_len = 2  # Минимальная длина индексируемого слова
index_exact_words = 1 # Храним и оригинальное слово в индексе
expand_keywords = 1 # Расширяем поисковый запрос до трех запросов

And you will collect the largest number of matches, but there will probably be a lot of garbage. You need to play around with the settings to find the one that suits you best.
