Question

Thinking Sphinx gives a error on searching some special chars like /, ) etc.
I thought adding them to the charset_table configuration in sphinx.yml would solve the problem, but it didn’t.

What I did was:

charset_table: "0..9, a..z, _, @, A..Z->a..z, /"

I even tried adding U+002F to the charset table, but it also didn’t work.

So what’s the best possible solution for this?

1. Something like the above, although it didn’t work for me? May be I am wrong somewhere?
2. Escaping the “search term” before querying Sphinx?

Answer 1

I’ve run in to this same issue. Try escaping the string you are querying against using Riddle.escape.

So a search might be:

Post.search(Riddle.escape("$foo@bar/something") # no idea why you would search for that
