Oleg, Teodor, folks:
I was demo'ing phrase search for a meetup yesterday, and the user
feedback I got showed that there's a missing feature with phrase search.
Let me explain by example:
'fix <-> error' will match 'fixed error', 'fixing error'
but not 'fixed language error' or 'fixed a small error'
'fix <2> error' will match 'fixed language error',
but not 'fixing error' or 'fixed a small error'
'fix <3> error' will match 'fixed a small error',
but not any of the other strings.
This is because the # in <#> is an exact match.
Seems like we could really use a way for users to indicate that they
want a range of word gaps. Like, in the example above, users could
'fix <1:3> error'
... which would search for any phrase where "error" followed "fix" by
between 1 and 3 words.
Not wedded to any particular syntax for that, of course.
That could be useful. I would like to add another idea here about
leaving out one side of the range.
'fix <:3> error'
'fix <2:> error'
To either indicate 1 (left) or unbounded (right).
