exact matches not possible?

[Jörg Kiegeland]

Normally I do substring-queries on my field named X. Now however I also 
require exact-match queries, however I do not know how to do this!

If I do
X:"blabla"

or

X:blabla


.. all documents containing "blabla" in field X are returned. However 
these are much too much, since I know there is exactly one  document 
matching "blabla" on field X exactly.
One solution would be to filter the search result for exact-matches on 
client side - however can I shift this filtering to Solr somehow?
