How to use regex for querying in Solr 4 - regex

Question

I've reached the point of desperation, so I'm asking for help. I'm trying to query results from a Solr 4 engine using regex.
Let's asume the document I want to query is:
<str name="text">description: best company; name: roca mola</str>
And I want to query using this regex:
description:(.*)?company(.*)?;
I read in some forums that using regex in Solr 4 was as easy as adding slashes, like:
localhost:8080/solr/q=text:/description\:(.*)?company(.*)?;/
but it isn't working. And this one doesn't work either:
localhost:8080/solr/q=text:/description(.*)?company(.*)?;/
I don't want a simple query like:
localhost:8080/solr/q=text:*company*
Since that would mismatch documents like:
<str name="text">description: my home; name: mother company"</str>
If I'm not clear please let me know.
Cheers from Chile :D
NOTE: I was using text_general fields on my scheme. As #arun pointed out, string fields can handle the type of regex I'm using.

Answer 1

Instead of trying regex search on text field type, try it on a string field type, since your regex is spanning more than one word. (If your regex needs to match a single word, then you can use a text field.)
Also do percent encoding of special characters just to make sure they are not the cause for the mismatches.
q=strfield:/description%3A(.*?)company(.*?)%3B.*/
Update:
Just tried it on a string field. The above regex works. It works even without the percent encoding too i.e.
q=strfield:/description:.*?company.*?;.*/
