How to write sphinx queries with OR condition

阅读更多关于 How to write sphinx queries with OR condition

问题 I need to create a sphinx query in my project with OR condition. But giving an OR condition like select cost FROM transactionsChart WHERE cost=25 OR cost=5; is not working. It returns an error like ERROR 1064 (42000): sphinxql: syntax error, unexpected OR, expecting $end near 'OR cost=5' Can anybody help me.... Thanks in advance 回答1: Sphinx doesnt support OR in the WHERE clause, only AND . For your specific example, could use IN syntax, sphinxql> SELECT cost FROM transactionsChart WHERE cost

Sphinx Search how to use an empty before_match and after_match

阅读更多关于 Sphinx Search how to use an empty before_match and after_match

问题 Using Sphinx's SNIPPET() function, how can I remove any before_match and after_match from my query? I don't want anything wrapped around the matching text. SNIPPET(field, 'word', 'after_match=""', 'before_match=""') I've tried after_match="" but this adds literal quotes to the match. I've tried after_match=''" but this fails I've tried after_match= and this fails too Any suggestions? 回答1: My only suggestion is just to set it to some innocuous string, and then remove in post. 'after_match=*'

Django-sphinx result filtering using attributes?

阅读更多关于 Django-sphinx result filtering using attributes?

问题 I was going through the django-sphinx documentation, and it looks like it allows you to filter search results using attributes , queryset = MyModel.search.query('query') results1 = queryset.order_by('@weight', '@id', 'my_attribute') results2 = queryset.filter(my_attribute=5) results3 = queryset.filter(my_other_attribute=[5, 3,4]) results4 = queryset.exclude(my_attribute=5)[0:10] From some examples, these attributes seem to be something you specify in the sphinx configuration file, rather than

It's like WHERE id = 1 AND id = 2 WHICH

When searching for 'bmw 330ci' results as the above will be returned, but, WITH AND WITHOUT the ci extension. There are a nr of extensions in cars as you all know (i, ci, si, fi etc). I want the 'minus sign' to 'exclude' all returns

阅读更多关于 thinking sphinx ordering by mixing capitals and lower case

问题 I have a rails application that is using thinking_sphinx for the searching. My problem is that the result returned is sorted with capitals first and lower case after it at the bottom. I'd like to mix them so that both 'A' and 'a' comes before 'B'. This is the method I'm using: Company.search(query, :star => true, :page => params[:page], :per_page => 20, :order => :name, :sort_mode => :asc) 回答1: Maurício's answer is almost on the right track - but that's for transforming the text that Sphinx
