Hi All,

I'm using Lucene on a site that has split content with a branch containing
pages in English and a separate branch in Chinese.  Some of the chinese
pages include some (untranslatable) English words, so when a search is
carried out in either language you can get pages from the wrong branch. To
combat this we introduced a language field into the index which contains
the standard language codes: en-UK and zh-HK.

When you parse a query  e.g. language:"en\-UK" you could reasonably expect
the search to recover all pages with the language field set to "en-UK" (the
minus symbol should be escaped by the backslash according to the FAQ).
Unfortunately the parser seems to return "en UK" as the parsed query and
hence returns no documents.

Has anyone else had this problem, or could suggest a workaround ?? as I
have
yet to find a solution in the mailing archives or elsewhere.

Many thanks in advance,

Alex Bourne
