In 4.0, your first query can be done with a regex query - enclose the
pattern in slashes:
q=/art(.*?)le/
Wildcards, fuzzy query, and regex query can only be applied to a single
term, so you can't do your latter "proximity" query. The best you can do is
a conjunction:
q=he+sa*
Although in that specific case you might simply expand the terms and use
explicit terms in a proximity query:
q="he+says"+OR+"he+said"+OR+"he+saw"+OR+"he+saved"+OR+"he+saves"
I think there is an alternative query parser that supports wildcards in
phrases, but the name escapes me at the moment.

Subject: Solr - Use Regex in the Query Phrase
Hi;
I am working with apache-solr-3.6.0 on windows machine. I would like to be
able to search for certain phrase which include some regex.
For example: I want my query to be: "art(.*?)le"
or another example of a phrase: "he sa*"
I dont know how to do that in the url that will be sent to solr. I would
like to be able to do something like that:
http://localhost:8983/solr/core0/select/?q="ar(.*?)cle"&version=2.2&start=0&rows=2&debugQuery=on&hl=true&hl.fl=*
or
http://localhost:8983/solr/core0/select/?q="he
sa*"&version=2.2&start=0&rows=2&debugQuery=on&hl=true&hl.fl=*
Here is the part of my schema that I am using
<fieldType name="text_ar" class="solr.TextField"
positionIncrementGap="100">
<analyzer>
<tokenizer class="solr.WhitespaceTokenizerFactory"/>
</analyzer>
</fieldType>
<field name="text" type="text_ar" indexed="true" stored="true"
termVectors="true" multiValued="true"/>
Any Ideas, please?
