Hi!

Invenio uses the colon : to tell the search engine the field to search.

Per see this is nice, but unfortunately, the colon is not really a good
separator in bibliographic data search. E.g. it usually separates the
main title from the subtitle as well. An example would be:

http://juser.fz-juelich.de/record/21825

reading

The Mont-Blanc Project: European Summit of Exascale System Architectures

Now, if you have the exact title you can copy&paste it into the search
box but it will yield no result as project: seems to trigger something
here. If I give the title in quotes (" or ') everything is fine. If I
remove the colon, everything is fine again. Just a literal copy&paste fails.

From this I would suggest to improve the search engine a bit. It seems
reasonable, that

- if the term in front of a colon is NOT a defined index nor a marc
field, it should not trigger a field search. Probably it is safe in
those occasions to strip the colon.

- if the letter following the colon is a blank it does not refer to a
field but is a literal colon.

I may add that at least for books there is also a separation common
(default RAK behaviour, ie. all german speaking library catalogues) that
is defined as " : " ie a colon enclosed in spaces. Might be that the
search engine doesn't like that either. At least if I add a space to the
above title I get some funny comment from invenio.
