I have a strange issue with Sphinx, I am trying to be able to match things like:
L.A. Confidential
So people can search for "LA Confidential" and still get that title. Similarly for "P.M." to be able to match "PM", etc.
I tried putting the period (full stop character U+002E) in the ignore_char list. This didn't make any difference.
So then I tried implementing index_sp =1. This did not solve the issue either.
According to what I understand of the documentation, either of these should have solved this issue correct?
I wonder if it has somthing to do with our math mode which is set to extended2, using Sphinx 2.0.3.
Any help would be greatly appreciated.
Edit, here is my thinking_sphinx.yml config:
Note that the period character (U+002E) is not used anywhere else in my config except in the ignore_chars line.

I ran a test locally with the following in my thinking_sphinx.yml for Thinking Sphinx v3.0.4 and it worked:
development:
ignore_chars: U+002E
The same in sphinx.yml for Thinking Sphinx v2.0.14 worked too. I am using Sphinx 2.0.8, but I'll be a little surprised if that's the problem. It's certainly unrelated to your match mode.
