The context for this is that I'm migrating an application from Solr 3.5 to 4.4.
We had regex search working (in kind of a hacky way), but since 4.x has regex
search support built in, I'm trying to switch to that. Some things work the way
I'd expect, some clearly don't. So my question was, in the first instance "Is
there full regex support?" Clearly, there's supposed to be, so something is
wrong, or I don't know the right escape syntax.
I think our definitions of "good documentation" differ :-).
Nevertheless,

Using the admin webapp query form, the following search works:
1)
untokenized_ia:/.*νιν.{1,20}ασκλα.*/
this corresponds to:
http://localhost:8083/solr/pn-search/select?q=untokenized_ia%3A%2F.*%CE%BD%CE%B9%CE%BD.%7B1%2C20%7D%CE%B1%CF%83%CE%BA%CE%BB%CE%B1.*%2F&wt=xml&indent=true
2) works as well
untokenized_ia:/.*νιν.{1,20} ασκλα.*/ (with a plain space before ασκλα)
http://localhost:8083/solr/pn-search/select?q=untokenized_ia%3A%2F.*%CE%BD%CE%B9%CE%BD.%7B1%2C20%7D+%CE%B1%CF%83%CE%BA%CE%BB%CE%B1.*%2F&wt=xml&indent=true
3) returns no results
untokenized_ia:/.*νιν.{1,20}\bασκλα.*/ (with a word boundary before ασκλα)
http://localhost:8083/solr/pn-search/select?q=untokenized_ia%3A%2F.*%CE%BD%CE%B9%CE%BD.%7B1%2C20%7D%5Cb%CE%B1%CF%83%CE%BA%CE%BB%CE%B1.*%2F&wt=xml&indent=true
untokenized_ia:/.*νιν.{1,20}\\bασκλα.*/ also fails. As does
untokenized_ia:/.*νιν.{1,20}\sασκλα.*/
