Lucene has a syntax “foo bar”~10 for finding foo within 10 words of bar.
Does ferret support this feature? (the ~ is used for fuzzy queries) Does
rdig?
This could be a deal breaker for me 'cos I really need proximity
searches

sure … take a look at this (take from the API):
–snip–
query = SpanNearQuery.new(:slop => 2)
query << SpanTermQuery.new(:field, “quick”)
query << SpanTermQuery.new(:field, “brown”)
query << SpanTermQuery.new(:field, “fox”)
|______2______^
|__1__^
^_____2_____|
A SpanNearQuery is like a combination between a PhraseQuery and a
BooleanQuery. It matches sub-SpanQueries which are added as clauses but
those clauses must occur within a slop edit distance of eachother.

and even better, you can force the order of the words… the above
example
doesn’t care about the order of the words, but if the order is important
to you, you can build queries that will search for terms in order and a
maximal distance between the words…

it’s okay to doubt ferret… sooner or later you will be convinced
happy ferret’ing …
