Keep in mind that this would not work for
important:"conference agenda"
as the quotes would be escaped and queryparser will not generate a phrase query

static String QueryParser.escape(String) should do the trick:

Look at the bottom of the below-linked page for the list of characters
that the above method will escape:

if you scan the query and escape all colons (ie \:) then you should be
good (I have not verified). Of course you will not be able to do a field
search, but that seems to be what your after.

Hi,
I have a search UI that allows search criteria to be input against
specific fields, e.g. Subject.
In order to create a suitable Lucene Query, I must analyze that String
so that it becomes a set of Tokens which I can then turn into Terms.
QueryParser seems to fit the bill for that, however, it is too clever
as it assumes that anything suffixes with a : is a field reference.
If someone enters
important:conference agenda
in the subject field, I don't want QP to translate this to
+important:conference +defaultfield:agenda
I want to end up with
+subject:important +subject:conference +subject:agenda
I've written something to do this, but I know it is not as clever as
QP as currently it can only create BooleanQueries with TermQueries and
cannot handle PhraseQuery, so would not handle
important:"conference agenda"
correctly. Does anyone have any pointers on how to limit QueryParser
so that I can force it to treat what it thinks as fields as terms.
Thanks
Antony
