Customize COMPLEX_QUERY_OPERATORS_PATTERN in query config

[YegorKozlov]

It would be nice to let users ability to override COMPLEX_QUERY_OPERATORS_PATTERN from query configuration.

In my case I had to spend quite a bit of time understanding why queries containing a dash are not expanded, e.g. vendor-managed is not expanded because the dash character is in COMPLEX_QUERY_OPERATORS_PATTERN .

I would like to be able to customize it from configuration instead of changing the source code.

Hm, that's actually a really interesting problem. I disagree with the proposed solution, though; I think the COMPLEX_QUERY_OPERATORS_PATTERN should just be smarter about ignoring hyphens. In fact, the hyphen is considered a complex operator in cases like this:

super -duper
super - duper

but not this:

super-duper

So unfortunately I would need to better understand when the hyphen is part of a single token and when it's surrounded by token-breaking whitespace (or other token-breaking characters).

Just giving you the option to specify this pattern is actually not going to fix anything, because if you remove the hyphen from the regex, then we won't properly be able to detect cases where there truly are complex operators.

Need some time to think about this bug...

Looks like I fixed this in a duplicate issue: #32.
