Thank you for your answer. I tried to use EdgeNGram under the same settings
<filter class="solr.EdgeNGramFilterFactory" minGramSize="3" maxGramSize="25"/> the same problem emerged, the search was not exactly correct. For instance, I need to find the figure 311570, I enter 3115 into the search bar, in the result I get all the figures that start from 311 and not 3115. Should I probably had to turn on this option for indexing only? But I'm still concerned with the fact that in case of this option Solr often crashed during indexing. How to turn on debug correctly so as to show you detailed errors? ====RU ==== Спасибо за Ваш ответ. Я пробовал использовать EdgeNGram при таких же настройках <filter class="solr.EdgeNGramFilterFactory" minGramSize="3" maxGramSize="25"/> возникала такая же проблема, был не совсем правильный поиск. Например надо найти число 311570 в поиск я ввожу 3115, в результате я получал все числа которые начинались на 311 а не 3115. Возможно данную опцию надо было включить только для индексации ? Но меня все равно беспокоит, что при данной опции часто в процессе индексации падал Solr. Как правильно включить debug что бы Вам показать более детальные ошибки ? 2017-12-28 22:47 GMT+01:00 Mikhail Khludnev <m...@apache.org>: > Obviously, Chris has nothing in common with Christmas, hence this classic > search behavior is correct. > What people are asking here is autocomplete, and it's a separate UX and > algorithms. > You can start to explore different aspects of this field from > https://lucidworks.com/2015/03/04/solr-suggester/ > You see NGamming just freak the heap out.
